Abstract 
This paper presents the static and dynamic flexural behavior of reinforced concrete beam based on a four-point bend test accompanying with the acoustic emission monitoring (AE) throughout the entire the load test. The dynamic load test starts with a load range from 10% to 80% of yielding load which is determined from the static load test, followed by increasing the upper load level to the post-yielding region with 1, 10, 100 and 1,000 of cycle numbers to examine the stiffness decay of the concrete beam until failure. Three loading rates of 0.5 Hz, 1.0 Hz and 2.0 Hz were adopted for dynamic load test. The test results showed that the concrete beams perform flexural behavior with a stable failure as being subjected to static load and with a sudden crushing manner as being subjected to dynamic load. Furthermore, the slower the loading rate, the more destructive it is to the concrete beam, the lower its bearing capacity, and the faster its stiffness decays. AE can reveal the disintegration processes inside reinforced concrete beams and provide early warning before failure occurs when the beam is subjected to static or dynamic loads.

Abstract 
Taiwan is located at an active plate boundary and is frequently affected by earthquakes. Many urban areas contain aging reinforced concrete (RC) buildings that may experience significant nonlinear response and damage during strong ground shaking. Therefore, assessing their seismic risk before future earthquakes is important for retrofit prioritization, disaster mitigation planning, and post-earthquake resource allocation. Conventional regional risk assessments often rely on empirical or simplified fragility curves, which may not fully capture the structural characteristics and nonlinear seismic behavior of individual buildings. Although probabilistic seismic risk assessment can provide more physics-based building-level risk estimates through nonlinear dynamic analyses and fragility functions, its application to city-scale building inventories requires a large number of repeated analyses and thus faces substantial computational challenges. To address this issue, this study develops a high-performance computing (HPC)-based framework for city-scale probabilistic seismic risk assessment. The framework integrates building inventory processing, automated structural model generation, incremental dynamic analysis, response post-processing, and fragility curve development. It is implemented on the National Center for High-performance Computing (NCHC) Forerunner 1 supercomputer, where dynamic task allocation is used to distribute building-level analyses across multiple central processing unit (CPU) cores. A case study is conducted for 62,454 RC buildings constructed before 1999 in Hualien County. Representative low-, mid-, and high-rise frame models are developed, and incremental dynamic analyses are performed using multiple ground-motion records and peak ground acceleration levels. The resulting fragility curves are further combined with ground-motion data from the 2024 Hualien 0403 earthquake to estimate building damage and compare the predictions with observed damage data. The results demonstrate the feasibility of using HPC for high-resolution city-scale seismic risk assessment.

Abstract 
Offshore wind turbines installed in seismic regions may be affected not only by wind and wave
loads but also by earthquake excitation, which can threaten structural safety. Therefore, effectively
reducing the structural dynamic response under seismic loading has become an important issue in
vibration control for offshore wind turbines. As turbine capacity and structural scale continue to
increase, conventional single tuned mass dampers (STMD) may show reduced control performance
because they are highly sensitive to tuning frequency. When structural frequency shifts and detuning
occurs, their vibration mitigation efficiency can decrease significantly. To improve the robustness and
efficiency of the control system, this study investigates a jacket-type offshore wind turbine structure
while considering the dynamic characteristics of the RNA. The control performance of single tuned
mass dampers (STMD), multiple tuned mass dampers (MTMD), single tuned mass damper inerters
(STMDI), and multi-tuned mass damper inerters (MTMDI) under seismic loading is evaluated.
In addition, the inverse element exchange method with multi-level programming (MulIEEM) and
the inverse element exchange method with greedy algorithm (GIEEM) are applied to optimize the
damper configuration. The differences between these optimization methods are compared in terms
of search efficiency, convergence behavior, and vibration reduction performance. The results show
that, under multiple earthquake time-history analyses, the MTMDI with inertance elements can
effectively reduce structural responses in most cases and demonstrates better control performance.
Both MulIEEM and GIEEM can improve damper configuration and enhance vibration mitigation
effectiveness. Overall, the proposed damper configuration and optimization methods can improve
the vibration control capability of offshore wind turbines under seismic loading and may serve as a
reference for future vibration control system design and engineering applications.

Abstract 
The construction industry is currently facing the dual challenges of net-zero carbon emissions
and intelligent construction. Three-dimensional concrete printing (3DCP) offers a promising
solution by combining material efficiency with automated construction. This study investigates
the incorporation of biochar, which has carbon sequestration potential, into 3D-printed
cementitious mortar as a partial mass replacement for the premixed non-shrink cementitious
product. The effects of biochar addition on rheological properties, mechanical performance, and
printability were systematically evaluated. A series of mortar mixtures with biochar replacement
ratios of 0.0%, 5.0%, 10.0%, 12.5%, and 15.0% was designed and tested. Various experiments
were conducted to examine the fresh and hardened properties of the mixtures. Manual printing
tests were further performed to simulate extrusion and layer-by-layer deposition, allowing the
buildability and practical feasibility of the mixtures to be assessed. The results are expected to
provide design guidelines for biochar-based 3DCP mortar and practical references for developing
sustainable buildings and low-carbon construction materials. This study supports the transition of
the construction industry toward intelligent and carbon-negative construction.

Abstract 
The knife-plate-connected seismic stud column (KSC) is a novel component applied in
special moment-resisting frames (SMF) to enhance energy dissipation efficiency. The KSC
consists of a steel shear panel damper (SPD) and boundary columns on both sides, which are
linked at both ends through knife-plate connections. This innovative design effectively adjusts
the deformation demands of the SPD, thereby improving its deformation capacity. This study
investigates the influence of axial loads on the seismic performance of KSCs through a two-stage
experimental program and verifies the effectiveness of an improved knife-plate connection design
(IKSC). A design methodology for boundary columns, including the transition zone (TZ) and
end connection (EC), is proposed. Experimental results indicate that applying axial loads has no
significant impact on the seismic performance of the KSC, though the cross-sectional dimensions
of the knife plate must be verified. Furthermore, by synthesizing historical research data, this
study establishes width-to-thickness ratio limits for KSC and IKSC sub-panels. The tests confirm
that the improved knife-plate connection of the IKSC effectively prevents fractures at the joints,
significantly enhancing the cumulative plastic deformation capacity of the component. Finally, a complete design procedure for KSC and IKSC systems is established and validated through experimental results.

摘要

 

本文主要在研究鋼筋混凝土簡支梁承受四點彎曲反覆載重下之行為，並全程以
音射法進行監測，研究鋼筋混凝土梁在靜態及動態彎曲的破裂行為。試驗中之動載 試驗，係從靜載試驗所得降伏荷載之 10–80% 範圍開始，隨後將荷載上限逐漸增加
到構件達降伏載重，在循環 1、10、100 和 1,000 次後，即檢驗混凝土梁之勁度， 觀察其勁度衰減的情形，直至破壞為止。動態載重試驗則採用 0.5
Hz、1.0 Hz 和 2.0 Hz 三種加載速率。試驗結果發現，混凝土梁在靜態載重作用下可呈現穩定破壞的 彎曲行為；但在動態載重作用下，會呈現瞬間壓潰的彎曲行為。另外，加載速率越
小，對混凝土梁的破壞性愈大，承載力愈低，且勁度衰減也愈快。利用音射監測法， 可瞭解鋼筋混凝土梁內部解構的過程，亦可提供混凝土梁構件在承受載重破壞前的

摘要

 

離岸風力發電機設置於地震帶地區時，除承受風、浪等環境荷載外，亦可能
受到地震作用影響而危及結構安全，因此如何有效降低地震作用下之結構動態反 應，已成為離岸風機振動控制之重要課題。隨著風機容量與結構尺度持續增加，
傳統單一調諧質量阻尼器 (single tuned mass damper, STMD) 因對調諧頻率具有高

量轉子與機艙總成 (rotor-nacelle assembly, RNA) 動態特性，探討 STMD、多重調 諧質量阻尼器 (multiple

STMDI) 及多重慣質式調諧質量阻尼器 (multiple tuned mass damper inerter, MTMDI)
於地震荷載作用下之控制效能。此外，本研究 結合多階層規劃逆元素交換法 (inverse element exchange method with
multi-level programming, MulIEEM) 與貪婪式逆元素交換法 (inverse element exchange method
with greedy algorithm, GIEEM) 進行阻尼器最佳化配置，並比較不同方法在搜尋效
率、收斂特性與減振效果上之差異。研究結果顯示，在多筆地震歷時分析中，引入 慣質元件之 MTMDI 多能有效降低結構反應，展現較佳控制表現；而
MulIEEM 與 GIEEM 皆可改善阻尼器配置並提升減振效能。整體而言，本研究所建立之阻尼器
配置與最佳化方法，可提升離岸風機於地震荷載作用下之振動控制能力，並可作為 後續減振系統設計與工程應用之參考。

Abstract  
Accurate shear strength prediction of reinforced concrete (RC) squat walls with different shapes is critical for structural safety and design in RC buildings using dual systems. However, wall shear strength equation in current Design Specifications for Concrete Structures (Civil 401- 112) exhibits significant scatter due to lack of a rational force transfer mechanism and limited parameter considerations. This study develops an analytical model based on the softened strutand-tie (SST) approach to improve shear strength predictions. A simplified equation for the concrete strut area is derived through curve approximation, enhancing computational efficiency of the SST model while maintaining accuracy. The proposed SST model is validated using experimental data from 281 squat walls, including rectangular, barbell, and flanged walls, and this study further presents a closer look into Civil 401-112 and American Concrete Institute (ACI) 318-25 code equations. Results show that the proposed model achieves competitive accuracy in both general shear strength and maximum shear strength predictions, offering a robust and mechanics-based model for wall shear capacity estimation.

Abstract  
Taiwan, located in the Pacific Ring of Fire, experiences frequent earthquakes that pose significant risks to urban buildings. Conventional post-earthquake building damage assessment primarily relies on manual field inspections, which are time-consuming, costly, hazardous, and often subject to human judgment. To address these limitations and the scarcity of real-world damage data, this study proposes an automated post-earthquake building damage classification framework that integrates physics-based collapse simulation with deep learning. A simulationdriven data generation workflow is developed using the open-source 3D software Blender coupled with the bullet constraints builder (BCB) physics engine. Based on the discrete element method (DEM), large-scale synthetic point cloud datasets with explicit physical attributes are generated and manually labeled in accordance with established domestic and international standards for post-disaster assessment. For automated damage classification, the PointNet deep learning architecture is adopted, and K-fold cross-validation is applied to ensure robust model training and evaluation. Experimental results show that the proposed model achieves an average classification accuracy exceeding 95.00% on validation datasets structurally consistent with the training data. Moreover, an accuracy of 86.67% is maintained on an independent test dataset, indicating promising generalization capability and knowledge transfer potential. The results demonstrate the feasibility of combining synthetic collapse simulation data with deep learning for the automated assessment of post-earthquake building damage.

Abstract  
This study proposes a simple seismic retrofit method for typical low-rise street-houses in Taiwan by attaching steel members to reinforced concrete (RC) frames with chemical anchors. Full-scale column and frame cyclic lateral loading tests were conducted to verify its feasibility and effectiveness. Two connection types of retrofitting steel members were designed: compression connections and moment connections. Test results indicate that both significantly enhance the lateral stiffness and strength of retrofitted structures, effectively mitigating the common softfirst-story problem in street-houses. While moment connections provide higher strength with some potential reduction in ductility, compression connections yield slightly lower strength but maintain ductility and reduce anchorage demands on beam bottoms. The method requires no foundation excavation, can be installed entirely within the frame, and minimizes cost, time, and user disruption. A pushover analysis model and a simplified strength estimation method were also developed and validated, providing reliable tools for practical seismic assessment.

Abstract  
Existing reinforced concrete (RC) structures frequently demonstrate insufficient shear resistance owing to non-ductile detailing, rendering them vulnerable to brittle failure during seismic events. This study examines the alternative application of carbon fiber-reinforced polymer (CFRP) strings as a novel shear strengthening solution for RC T-beams. The CFRP strings were produced via a pultrusion and resin impregnation process, and thereafter integrated along the beam perimeter utilizing the near surface mounted (NSM) technique. Two beam specimens were subjected to testing under a two-point loading configuration to induce shear-critical behavior. Experimental observations indicated that CFRP string strengthening enhanced shear confinement and postponed diagonal crack propagation, leading to an increase in shear capacity and a significant enhancement in ductility. Analytical evaluation using the Indonesian Standard Code and Zararis’s model revealed that conventional design equations underestimated actual shear capacity, highlighting the necessity for updated formulations for beams with moderate shear span-to-depth ratios. Overall, the results demonstrate that CFRP strings serve as an efficient and lightweight retrofit option for enhancing the shear performance and deformation capacity of RC beams, presenting a sustainable solution for seismic strengthening applications.

Abstract  
Unbonded post-tensioned precast walls are recognized for their excellent seismic resilience due to a self-centering ability that minimizes post-earthquake repair needs. While this system offers significant advantages, conventional concrete walls often experience concrete crushing at the corners under large displacements, limiting their performance and axial load capacity. To overcome this limitation, this study investigates the application of ultra-high-performance concrete (UHPC) in unbonded post-tensioned precast walls and evaluates their seismic behavior. Following the design principles outlined in ACI (American Concrete Institute) 550.6 and ACI 550.7, two scaled wall specimens were tested under cyclic loading, one with conventional concrete and one with UHPC. Compared to the conventional concrete wall, The results demonstrate that the UHPC wall exhibited no significant cracking and showed superior self-centering and minimal residual displacement under the same axial load. Digital image correlation (DIC) analysis revealed that the UHPC specimen exhibited a more uniform strain distribution and suppressed compression concentration at the wall corners. The fiber-bridging effect effectively controlled crack propagation, resulting in a stable flexural-dominated response and delayed localized crushing. Overall, the UHPC specimen more effectively satisfied the performance objectives corresponding to the design basis earthquake (DBE) level, indicating enhanced strength and deformation capacity. Furthermore, finite element models of the walls were developed in OpenSees (Open System for Earthquake Engineering Simulation) and validated against the experimental data. These models accurately simulate the load-displacement behavior of unbonded post-tensioned precast walls, providing a reliable tool for future seismic performance assessment.

摘要
準確預測不同形狀剪力牆之剪力強度對鋼筋混凝土二元系統建築物的結構安 全與設計至關重要。然而，現行「建築物混凝土結構設計規範」（簡稱土木 401- 112）之牆剪力強度公式因缺乏合理的剪力傳遞機制，且考慮的影響參數有限，導 致其預測結果具有顯著的離散性。本研究基於軟化壓拉桿 (softened strut-and-tie, SST) 模型提出一套評估方法，以改善不同形狀剪力牆剪力強度的預測準確性。同 時，透過曲線近似推導出簡化的混凝土壓桿有效面積公式，在維持預測精度的情況 下提升計算效率。所提出之 SST 模型以 281 筆低矮型剪力牆試驗資料進行驗證，其 涵蓋矩形、啞鈴形及翼形牆，並進一步與土木 401-112、美國混凝土學會 (American Concrete Institute, ACI) 規範 ACI 318-25 公式進行比較。結果顯示，本研究所提出 的模型在剪力強度與最大剪力強度的預測上皆展現出良好的準確性，提供一種兼具 力學基礎且可靠的剪力牆剪力強度評估方法。

Abstract  
Accurate shear strength prediction of reinforced concrete (RC) squat walls with different shapes is critical for structural safety and design in RC buildings using dual systems. However, wall shear strength equation in current Design Specifications for Concrete Structures (Civil 401- 112) exhibits significant scatter due to lack of a rational force transfer mechanism and limited parameter considerations. This study develops an analytical model based on the softened strutand-tie (SST) approach to improve shear strength predictions. A simplified equation for the concrete strut area is derived through curve approximation, enhancing computational efficiency of the SST model while maintaining accuracy. The proposed SST model is validated using experimental data from 281 squat walls, including rectangular, barbell, and flanged walls, and this study further presents a closer look into Civil 401-112 and American Concrete Institute (ACI) 318-25 code equations. Results show that the proposed model achieves competitive accuracy in both general shear strength and maximum shear strength predictions, offering a robust and mechanics-based model for wall shear capacity estimation.

Abstract  
Taiwan, located in the Pacific Ring of Fire, experiences frequent earthquakes that pose significant risks to urban buildings. Conventional post-earthquake building damage assessment primarily relies on manual field inspections, which are time-consuming, costly, hazardous, and often subject to human judgment. To address these limitations and the scarcity of real-world damage data, this study proposes an automated post-earthquake building damage classification framework that integrates physics-based collapse simulation with deep learning. A simulationdriven data generation workflow is developed using the open-source 3D software Blender coupled with the bullet constraints builder (BCB) physics engine. Based on the discrete element method (DEM), large-scale synthetic point cloud datasets with explicit physical attributes are generated and manually labeled in accordance with established domestic and international standards for post-disaster assessment. For automated damage classification, the PointNet deep learning architecture is adopted, and K-fold cross-validation is applied to ensure robust model training and evaluation. Experimental results show that the proposed model achieves an average classification accuracy exceeding 95.00% on validation datasets structurally consistent with the training data. Moreover, an accuracy of 86.67% is maintained on an independent test dataset, indicating promising generalization capability and knowledge transfer potential. The results demonstrate the feasibility of combining synthetic collapse simulation data with deep learning for the automated assessment of post-earthquake building damage. The proposed framework offers a scalable, costeffective, and automation-oriented solution that supports rapid post-disaster decision-making and enhances the digitalization of structural damage assessment workflows.
