作者劉光晏、宋裕祺、張國鎮
關鍵字高強度鋼筋混凝土、橋墩、耐震性能
摘要本研究採用高強度混凝土與高強度鋼筋材料（New RC），進行6 組單柱式橋墩之反覆載重實驗，檢討斷面、材料與配筋組合，使New RC 橋墩在承受相近柱軸力下可獲致與一般RC 橋墩相近之撓曲強度、位移韌性與消能能力。試體規劃包括RC 標準試體（BMRC1）、New RC 實心斷面試體（NEWRC1、NEWRC5）及New RC 空心斷面試體（NEWRCH1、NEWRCH2、NEWRCH3）。製作方式分為4 組場鑄及2 組預鑄節塊橋墩，其中NEWRCH3包含後置預力。實驗結果顯示，New RC 橋墩因配置10 cm 間距之橫向鋼筋提高良好的圍束效果，且高寬比大及軸力比低條件，結構行為滿足公路橋梁耐震設計規範有關強度與韌性規定，確實達成斷面及材料減量的目標。結合預鑄節塊及後置預力方式施工，更進一步提高施工效率與震後復原能力。此外，本研究以既有簡化模式分析，經比較實驗結果可快速且有效預測New RC 柱之側推曲線，達到耐震設計與評估之目的。
TitleFeasibility Study of New RC on the Seismic Design of Bridge Column
AuthorKuang-Yen Liu, Yu-Chi Sung, Kuo-Chun Chang
KeywordsHigh strength concrete and reinforcement, bridge column, seismic performance
AbstractThis study presents the experimental study on the seismic performance of bridge column with high strength concrete and reinforcements, called New RC column. Given a specified plastic moment strength resulted from a predetermined RC column with ordinary materials, the design objective of New RC column is to provide same plastic moment strength but reducing the cross section, quantities of longitudinal and lateral reinforcement simultaneously. Total of one RC column (BMR1), two solid-section New RC columns (NEWRC1, NEWRC5) and three hollow-section New RC columns (NEWRCH1, 2, 3) were manufactured by either cast-in-place or precast and carried out by cyclical loading tests. For New RC specimens, the design compressive strength of concrete, yielding strength of longitudinal and lateral reinforcement are 70, 685, and 785 MPa, respectively, while RC column are 28, 420, and 280 MPa. Experimental results demonstrated that New RC column with sufficient lateral confinement and subjected to relative small axial load ratio can effectively reduce cross section and usage of material without losing desired flexural strength, either equipped with solid or hollow section. Besides, applying posttensioned strands within NEWRC column can provide self-centering mechanism to eliminate residual displacement. In addition, the pushover curve can be well predicted by the conventional program. The seismic performance of New RC column has been confirmed and its application can be expected in the future.

摘要本文目的是利用橋樑抖振理論與風洞實驗所得之氣動力參數，提出一等值靜力風載重表示式，使橋樑設計工程師能以此等值靜力風載重與其他型式載重做組合，以利結構分析及設計使用。等值靜力風載重包含靜、動態風力效應，其中動態效應分別考慮背景及共振部分。本文背景部分分別採用LRC(Loading Response Correlation)法及慣性力分佈型式，並比較兩者之差異，而共振部分則是依慣性力分佈型式。本文以一簡支樑及一斜張橋為例，前者是用來與文獻結果做比對，來驗證此方法之正確性；而後者則是利用兩種方式分別推導其等值靜力風載重，一為利用風力係數、顫振導數及理論頻譜推導，二為利用斷面模型風洞實驗所量測之位移來推導其等值靜力風載重。
TitleApplication of equivalent static wind loads on bridge design
AuthorYuh-Yi Lin, Ping Wang
Keywordsequivalent static wind loads, bridge design, buffeting, section model, wind tunnel test
AbstractIn this paper, an approach to generate the equivalent static wind loads at the design wind speed based on buffeting theory and the information obtained from wind tunnel tests is presented. Using this approach, bridge engineers are able to obtain the equivalent static wind loads and then easily to combine these wind loads with other loads for use of structural analysis and design. The equivalent static wind loads include static and dynamic effects. The dynamic effects are generally divided into the background and the resonant components. Two methods to generate the background components are presented in this paper. One is LRC approach and the other is based on the inertia load distribution. The comparison of the results between these two methods is discussed. The resonant components basically follow the inertia load distribution. Two examples, including a simply supported beam and a cable-stayed bridge, are used to examine the validity and applicability of the approach. Two types of equivalent static wind loads are generated in the cable-stayed bridge example. One is derived from buffeting theory utilizing static force coefficients, flutter derivatives and wind force spectrum. The other is formulated based on the responses measured from the section model tests.

摘要在地震頻繁區域中，耦合結構牆經常使用於中高樓層結構系統，提供側向勁度，抵抗地震外力，並減少結構體之側向位移。本文章探討複合耦合結構牆抗震系統之側推行為，研究耦合率與耦合牆高度對於複合耦合結構牆行為之影響。本研究統整國外之建議設計方法，設計九座複合耦合結構牆，並建立其非線性數值分析模型，分別具有三種不同耦合率，與三種不同高度，分別為20%的低耦合率，40%的中等耦合率，與60%的高耦合率；10層樓的低樓層，20 層樓的中高樓層，與30 層樓的高樓層。耦合牆之行為採用非線性側推分析方法進行預測，並比較各耦合牆之受力機制、變位大小、以及破壞模式，此外，並依據FEMA-356 所建議之兩種不同災害層級加以評估：分別為50 年超越機率10%之地震，代表生命安全之表現目標，以及50 年超越機率2%之地震，代表倒塌預防之表現目標。研究發現耦合牆不適合採用過低之耦合率，研究結果並對不同高度之耦合牆抗震系統，分別建議合適之耦合率範圍。
TitleDesign and nonlinear pushover analysis of earthquake-resistant hybrid coupled structural wall systems
AuthorChung-Chan Hung, Wei-Ting Lu
Keywordscoupled structural walls, nonlinear pushover analysis, earthquake-resisting behavior, structural design
AbstractCoupled structural walls are often used in mid- to high-rise structural systems in earthquake regions. This type of structures is able to provide efficient lateral stiffness to resist earthquake loading and reduce the lateral drift response of the entire structural system. The paper investigates the pushover behavior of hybrid coupled structural walls. The influences of the coupling ratio and structural height on the structural behavior are extensively investigated. Nine different hybrid coupled structural walls with three different coupling ratios and three different heights are designed. The coupling ratios are 20%, 40%, and 60%, respectively, and the structural heights are 10 stories, 20 stories, and 30 stories, respectively. The nonlinear finite element models of the nine designs are constructed. Their behavior is studied using nonlinear pushover analysis. The performance of the various systems is compared in terms of the earthquake-resistant mechanism, the displacement response, and the failure pattern. The evaluation criteria specified in FEMA-356 for 10% and 2% probabilities of exceedance in 50 years are employed for the assessment purpose. The study finds that it is not appropriate to design a coupled wall system with too low a coupling ratio. Suitable coupling ratios are suggested for coupled walls with different structural heights.

關鍵字非結構構件、耐震設計、設備耐震、設備地震力、設備加速度、設備隔震、柔性設備
摘要設備之耐震性為建物耐震工程中極重要的一環，因為重要設備若於地震中損壞將直接影響建物之使用功能，並造成經濟損失。而由於結構動態放大效應之故，設備之地震力需求與建物極為不同，應特別加以考量。現行耐震設計規範中有關設備之耐震分析與設計，係以非結構構材最小地震力公式加以規定。然而該公式並未考量建物及設備本身之動態特性，故易造成過於保守或低估設備地震力之情形。有鑑於此，本文乃利用反應譜及振態疊加原理重新推導建物中設備之地震力公式。在給定設計反應譜及建物與設備之動態參數(振頻及阻尼)條件下，該建議公式可推估設備在建物中不同樓層之最大地震力或最大加速度需求。惟該公式不適用於設備與建物發生共振之情況。為驗證公式之精確性，本文在數值案例中分別模擬一低頻(柔性)設備與一高頻(剛性)設備置於中低建物中之最大地震反應。經與歷時分析比較結果顯示，只要不是在共振區內，不論是低頻或高頻設備，本文公式所推估之樓層設備最大加速度反應皆遠較規範公式精準，且非常接近歷時分析之結果。其對於低頻設備之地震加速度反應推估尤其精準，此亦顯示本文建議公式極適用於具柔性之低頻設備，例如：隔震設備，細長塔架設備或管線設備等。
TitleA Seismic Design Formula For Equipment And Non-Structural Compments In Building Structures
AuthorLyan-Ywan Lu, Jiun-Hung Hung, Chia-Chiea Hsu
KeywordsNonstructural component, seismic design, seismic load, equipment protection, equipment isolation, acceleration response.
AbstractIn a building structure, the seismic capacity of equipment is an important issue, since it may cause serious functionality and financial losses of the building if the equipment is damaged in an earthquake. Due to the dynamic amplification effect of the underlying structure, the seismic demand of the equipment is very different from that of the primary structure and has to be treated with special attention. In current design codes, the seismic force of equipment is usually estimated by using the formula of the minimum seismic demand for nonstructural components. However, in this formula, the dynamic properties of the primary structure and equipment are not considered; therefore, the seismic force of the equipment may be over- or underestimated. To this end, based on modal superposition and response spectrum methods, a design formula is derived in this study. When the fundamental frequency and damping ratio of the primary structure and equipment are specified, the derived formula is able to estimate the seismic force or acceleration of equipment located on a certain floor level. Nevertheless, the formula is not applicable to the case in which the frequency of equipment is close to the resonance frequency of the structure. The accuracy of the formula is verified by using the data obtained from time history analysis of equipment placed on mid- and low-raised buildings. The simulation result demonstrates that the maximum accelerations of either soft or rigid equipment predicted by the proposed formula are far more accurate than the values predicted by the design code and are very close to the ones obtained from the time history analysis, particularly for low-frequency equipment. This indicates that the formula is particularly suitable for low-frequency equipment, such as base-isolated, slender or pipeline-type equipment.

KeywordsDual-core self-centering brace (SCB), Buckling-restrained brace (BRB), Cyclic test, Non-linear time history analysis of frames, Residual deformation
AbstractA new steel dual-core self-centering brace(SCB) is developed in Taiwan to have a flag-shaped re-centering hysteretic response under cyclic loads. Axial deformation capacity of the brace is doubled by serial deformations of two sets of tensioning elements arranged in parallel. In this paper, the mechanics of the new brace is first explained, followed by testing one SCB to evaluate its cyclic performance. Finite element analysis is conducted on the specimen to verify the mechanics and hysteretic responses observed in the test. Finite element analyses are also performed on other 16 dual-core SCBs to evaluate how tensioning element types, initial PT force, and friction force affect the cyclic performance of the brace. Additionally, three braced frames of varying heights are designed using two bracing members, SCBs and buckling-restrained braces (BRBs). Nonlinear time history analyses are conducted on these braced frames to obtain seismic demands under both design and maximum considerable levels of earthquake motions and near-field motions. SCB frames generally exhibit a smaller peak interstory drift and residual drift than BRB frames.

摘要本文針對RC與加強磚造建築物，建議一套新研擬之震害分級判定基準，此基準綜合了整體判定式與詳細判定式流程的優點，以能夠迅速、正確、客觀地於震後進行緊急震害分級為目標。此基準曾透過專業人員問卷方式，驗證其客觀性與對中等程度震害等級的辨識能力，結果顯示其合理可行且較偏保守。本文再以此分級基準對現地試驗校舍試體及三分之一縮尺RC校舍模型振動台試體進行評估，以探討震害等級與結構載重－位移曲線之對應關係，並與內政部現行緊急鑑定基準相互比較，以再次驗證其合理性。結果發現本文震害分級基準與內政部現行基準之判定逼間相符，並提出各種震害等級對應於載重·位移曲線之範圍。

Keywordsearthquake damage, load-displacement curve, reinforced concrete, confined masonry
AbstractAn earthquake damage evaluation procedure that is objective and easy to use for low-rise RC and confined masonry buildings is presented in this paper. The procedure is established by reviewing several existing procedures and integrating their merits. The accuracy of the procedure and its capability of distinguishing the medium damage states were verified by questionnaires to professionals in former research. It was found that the procedure can produce more accurate and conservative result than subjective judgment. In this paper, the procedure is applied to in-situ test and shaking table test specimens to validate the rationality of the evaluation factors and compared with the current damage evaluation procedure used in Taiwan. The comparison shows that the procedure is reasonable and consistent to the current procedure. The relationship between the determined damage states and the load-displacement curve is then summarized from the validation.

作者黃世建、Erwin Lim、翁樸文、李宏仁
關鍵字梁柱接頭、有效面積、抗剪有效寬度、偏心梁柱接頭
摘要現行之ACI 318-11 規範[1]參考了ACI-ASCE 352 規範委員會[2]之多項建議，定義梁柱接頭之剪力計算強度為平均剪應力容量與接頭有效面積之乘積。但多年之使用經驗顯示，ACI 318-11 規範[1]對偏心梁柱接頭抗剪有效寬度之規定過於嚴苛。本研究探討四種接頭有效寬度的計算方式，其中包含ACI 318-11 [1]、ACI 352R-02 [2]、AIJ Guidelines [3]與 NZS 3101 [4, 5]等規範。本文除了以資料庫實驗結果比較各規範有效寬度之差異，更進一步地提出接頭有效寬度之公式。本文提出的接頭有效寬度可反映各種矩形梁柱接頭之幾何尺寸變化差異，並可合理預測資料庫之偏心及同心梁柱接頭的剪力強度。本文所建議之接頭有效寬度，除可供接頭剪力強度設計之經驗公式使用外，其亦具有力學意義，而能應用在接頭剪力強度預測之解析模型中。此外，依據現有之同心外部(T 形)梁柱接頭實驗結果，本文也重新強調工程師在接頭區內需將梁主筋彎鉤延伸至柱核心區遠端錨定的重要性。
TitleDesign of Shear Strength for Eccentric Beam-Column Joints

Keywordsbeam-column joint, effective joint area, effective joint width, eccentric beam-column joint
AbstractThe current ACI 318-11 building code, which adopts many recommendations from ACI-ASCE Committee 352, defines the nominal joint shear strength of a beam-column connection as the product of the average shear stress capacity and the effective joint area. Past experience did indicate that the ACI 318-11 provisions on the effective joint width of the eccentric beam-column joints are too strict. This study critically evaluates four sets of effective joint width provisions, available in ACI 318-11, ACI 352R-02, AIJ Guidelines, and NZS 3101, as well as the companion provisions for average shear stress capacity. Comparisons and experimental verifications have been made among the code provisions; and more general expressions of effective joint width are proposed for design. The proposed effective joint width considers various sizes of rectangular joints and gives consistent strength estimations for both concentric and eccentric beam-column connections. Since the proposed effective joint width possesses the physical meaning of concrete crushing, it can be used both in the ACI 318-11 design method and the associated analytical procedures. Furthermore, based on available research data for concentric exterior (T-shaped) beam-column connection specimens, this study re-emphasizes engineers to extend beam longitudinal bars to the far face of the confined column core.

摘要臺灣校舍之數量龐大，且耐震能力堪虞，需以經濟、有效之方法篩選出耐震有疑慮之校舍，再以補強或重建之方式全面提升校舍之耐震能力。初步評估為一簡單且客觀之篩選方法，可快速估算出校舍結構之耐震容量與耐震需求。國家地震工程研究中心曾執行四次校舍現地試驗，針對梁柱構架試體進行初步評估並與試驗結果比較，初步評估之合理性已獲得驗證。臺灣校舍在縱沿走廊方向普遍有磚翼牆存在，為探討初步評估法對此種含磚翼牆校舍之保守性，本文以口湖國小現地試驗中一座含磚翼牆校舍試體為標的，該校舍之RC 柱斷面積與磚翼牆斷面積相當，從其材料強度、單位面積重量、極限基底剪力強度、基本振動週期、容許韌性容量及基本耐震性能，比較初步評估之估算值與現地試驗之實測或實算值。經檢核後，初步評估在材料強度、極限基底剪力強度及容許韌性容量之估算上，均為保守；在單位面積重量之估算上，該試體之磚牆量較高，故初步評估之估算值略為低估；在基本振動週期之計算，該校舍之磚翼牆提供強度和已達柱子側向強度和之30%，故採用規範所定各類建築物中週期最短之經驗公式計算，估算出之基本振動週期仍略高於實算值；在基本耐震性能方面，初步評估雖在校舍結構之全部靜載重低估，但因極限基底剪力與容許韌性容量低估，其基本耐震性能為現地試驗之51.7%，顯示此初步評估法為保守且具可行性。

Keywordsschool building, brick walls, preliminary evaluation, in-situ experiments
AbstractExisting school buildings in Taiwan are numerous and vulnerable under earthquakes so that economical and effective methods to screen those buildings with insufficient seismic capacity is necessary. Preliminary evaluation is a simple and objective screening stage in which seismic capacity and demand of an existing school building can be computed easily. The National Center for Research on Earthquake Engineering has conducted in-situ experiments in four schools. Preliminary evaluation of school buildings without brick walls has been validated. In Taiwan, school building with brick wing walls along the corridor direction is very common. In this paper, in-situ experimental results of a school building with brick walls at Kou-Hu Elementary School are adopted to verify the preliminary evaluation method. In this building, the cross-sectional area of brick walls is as much as that of columns. The material strengths, weight per unit floor area, ultimate base shear strength, fundamental vibration period, allowable ductility capacity and fundamental seismic performance from preliminary evaluation are compared with those from in-situ tests. From the comparison, preliminary evaluation is conservative in material strengths, ultimate base shear strength and allowable ductility capacity. Because of brick walls, preliminary evaluation underestimates the weight per unit floor area. Since the strength contributed by brick walls exceeds 30% of that contributed by columns, empirical formula with shortest vibration period stated in the seismic codes is adopted in the preliminary evaluation. However, it is still longer than the vibration period extracted from the in-situ results. As a whole, the fundamental seismic performance from preliminary evaluation is just 51.7% of that from in-situ experiment. Therefore, the proposed preliminary evaluation method is conservative and feasible.

關鍵字低強度鋼筋混凝土柱、耐震補強、擴柱、翼牆、反覆載重試驗
摘要本文針對低強度鋼筋混凝土柱進行耐震補強實驗研究，試驗結果顯示不管是擴柱或是增設翼牆補強都能有效提高側向抗剪強度，其中擴柱補強的韌性比及遲滯消能能力都遠優於增設翼牆補強。這是因為經擴柱補強後，其抗彎及抗剪的能力都能有效的提升，且試體係由撓曲破壞所控制，因而能提高韌性強度。另一方面，增設翼牆補強後，雖然抗剪能力得到有效的提升，但原柱柱體與翼牆卻分別發生彼此獨立的剪力破壞，且側向強度在位移相對較小時即達最大值。在側向強度達最大值之後，試體之強度及勁度隨即出現快速衰減，因而使韌性強度不佳，是以遲滯迴圈出現典型的剪力破壞模式以及嚴重的遲滯迴圈收縮現象。擴柱補強係將原柱柱體完全封閉式的包圍在中央核心，因此即使不考慮原柱的貢獻，外圍的補強體將如同一中空柱能獨立的抗彎抗剪，如此一來，不管原柱柱體與補強體是否能完全有效連結，擴柱補強都能穩定的提高耐震能力。雖然翼牆補強是希望透過植筋使新舊混凝土完全結合在一起共同抵抗外力，但因混凝土強度偏低植筋並無法達此目標，以致於原柱柱體與翼牆分別發生彼此獨立的剪力破壞，即使如此，翼牆補強由於優異的力學機制仍能達到有效提高抗剪能力的目的。

Keywordslow strength, reinforced concrete column, seismic retrofit, column jacketing, wing wall, cyclic loading test
AbstractIn this paper, the low strength RC columns were seismically retrofitted and cyclically tested. Test results reveal that either the column jacketing or wing walls can effectively increase the lateral shear strength. In addition, The RC jacketing can have a better improvement in capability of energy dissipation and in ductility when compared to installing wing walls. RC jacketing not only increases moment and shear capacity but also results in a flexural failure mode. Thus, the ductility increases. On the other hand, although RC wing walls can increase shear capacity, the original column and the wing walls cannot be integrated together and experience shear failure independently. After yielding the maximum lateral strength, the stiffness and strength are rapidly degraded and thus the specimen results in poor ductility. Apparently, the hysteretic loops can be classified as a typical failure mode, where stiffness degrading and strength degrading in addition to pinching are found. The jacket around the original column can be considered as a hollow column and thus it can resist both flexural moment and shear force. Consequently, RC jacketing can effectively increase the resistance to moment and shear whether the connections between the original column and new jacket are good or not. It is anticipated that the post-installed anchors can integrate the new and existing concrete together to resist seismic force for RC wing walls. However, this goal cannot be achieved due to the low strength concrete. As a result, an independent shear failure is found for the original column and the two wing walls. Even so, it is evident that RC wing walls can still enhance the shear capacity due to the very good mechanism.

AbstractThis paper establishes a numerical method to estimate post-earthquake financial loss of an individual RC building. Through nonlinear analysis and seismic performance evaluation, structural behavior subjected to an earthquake excitation can be estimated. Corresponding damage degrees can be determined accordingly. Financial loss in terms of the repair to replacement cost ratio of the most severely damaged storey is estimated based on the post-earthquake damage degree. As a result, the repair cost is obtained and it is clear whether the building needs rehabilitation or rebuilt after demolition. Finally, we take an old building and a lately designed building as examples to establish correlation curves between the spectral displacement and the repair to replacement cost ratio of the most severely damaged storey through nonlinear static pushover analyses. The method proposed in this paper helps decision-making of lifecycle maintenance and management of existing buildings. It also provides a method to control post-earthquake damage consequence and risk for the next-generation of performance-based seismic design.

AbstractThe steel dual-core self-centering brace (SCB) is a novel structural member that provides both energy dissipation and re-centering properties to structures under earthquakes. The axial deformation capacity of the brace is doubled by using two inner cores and one outer box and by serial axial deformations of two sets of parallel tensioning elements. A new cross-anchored dual-core SCB is proposed to reduce half the number of tensioning elements needed for applying the initial post-tensioning work compared to the original dual-core SCB, to investigate the potential use of high-strength steel tendons as tensioning elements, and to examinethe effects of number of cycles on the brace behavior, energy dissipation, and durability of the steel tendon-anchorage system.The mechanics and cyclic behavior of the new brace are first explained; a 7950-mm long cross-anchored dual-core SCB is tested six times. The cross-anchored dual-core SCB exhibits excellent self-centering property up to a lateral drift of 2.5% with a maximum axial load of 1700 kn. No damage of steel tendons, anchors or bracing members is found after three cyclic loading tests by AISC (2010) seismic provisions and 60 low-cycle fatigue tests. Finite element analysis is conducted to furtherverify the hysteretic responses and mechanics of the proposed cross-anchored dual-core SCB in the cyclic tests.

摘要臺北市社子大橋係採用一傾斜橋塔搭配二跨不對稱主梁跨徑(180m+70m)之鋼斜張橋。本橋主梁長短跨比高達2.57，除於短跨處設置壓重混凝土外，並採用造型新穎的傾斜橋塔，配合最佳化鋼索預力的施加，克服上部結構主梁及橋面板等靜載重因長短跨徑差異而產生不平衡力的影響，達到符合力與美的設計目標。本橋配合180m 中跨徑主梁之特性，採用自錨式(self-anchored)鋼索錨定方式，除滿足經濟設計之需求，在耐震設計方面依靜力分析進行設計，並採用動力歷時分析作為耐震性能檢核;在抗風設計方面，除依據橋梁設計規範之相關規定進行設計外，並以斷面模型及全橋模型之風洞試驗檢核相關空氣動力參數及受風反應，驗證本橋的的耐風性能並與設計階段風力作比對，確保本橋梁之耐風穩定。此外，為確保鋼索錨碇鄰近區域構造細節之安全性能，對錨碇區域進行有限元素局部應力分析，以判斷局部應力傳遞是否合宜。本橋在結構分析及設計上，有別於一般橋梁者，具備獨特性與困難度，為一難得之橋梁工程設計經驗，本文所得成果，冀可供為日後相關工程之參考。

AbstractBeing an asymmetric span configuration (180m+70m), the SheZi Bridge in Taipei was designed as an inclined pylon steel cable-stayed bridge.As the asymmetric span configuration has a ratio of main span to side span up to 2.57, the loading of the superstructure generated a huge unbalanced effect to the pylon and the girder. Therefore, the counterweight concrete was designed for unbalanced loading effect, and the inclined pylon and the optimization post-tensioning cable force analysis were used to reduce the unbalanced effects caused by the static load applied and for enhancing the aesthetics design. As the span has a length of 180m, we used a self-anchored cable system for this bridge. Though the static analysis result was used for structural design, the dynamic analysis was also required. For the dynamic analysis of this bridge, both the response spectrum method and the time history method were used. To verify the wind resistance of the bridge and to obtain the aerodynamic parameters, the cross section model and the full model for wind tunnel tests were done to ensure the performance of the bridge’s resistance to wind;and to make a comparison of the wind force during the design stage; and to double check the wind resistant design. In addition, to ensure the safety of the cable anchorage, the finite element analysis was done to verify the stress delivery. This article will take this bridge as an example, carry out the analysis and design of cable-stayed bridge with asymmetric span and inclined pylonhaving unique and difficulty, and provide as a reference for the engineering of related projects.
