耦合結構牆系統常應用於中高樓層結構中，以提昇整體結構系統側向勁度。因應實務上如開窗、安裝電梯井設置等需求，剪力牆常設置開孔，進而形成由兩座或以上之剪力牆，透過連接梁相互連接而成之耦合結構牆系統。
過往研究多著重於耦合結構牆系統之反覆載重測試，而為了進一步探討其耐震行為，國家地震研究中心(NCREE)與紐西蘭地震工程研究中心(QuakeCoRE)於2025年進行大型振動台實驗。實驗目標探討由剛性之耦合結構牆系統與柔性之鋼挫屈束制斜撐(BRBs)所構成之五層樓大型結構，在地震力作用下的相互作用行為。
本研究除著重於實驗所測得之連接梁耐震行為，亦建立OpenSees分析模型以與實驗成果進行比較。分析模型可分別應用於連接梁構件與整體耦合結構牆系統，並透過與既有文獻之實驗成果比對、驗證。為能捕捉連接梁之剪力與滑移行為，模型結合修正壓力場理論(modified compressive field theory, MCFT)與鋼筋混凝土構件之滑移機制。分析結果顯示，此模型能有效模擬在不同設計參數下，連接梁與耦合結構牆呈現之遲滯行為。
此外，鑑於耦合結構牆系統經常與外圍抗彎矩構架系統搭配使用，以提升結構使用空間，並形成具開孔之二元系統(dual system with openings)，本研究亦延伸提出適用於無開孔之二元系統(dual system without openings)之分析模型，並與2006年於日本E-Defense所進行之振動台實驗成果比對，以應用於未來不同結構系統之動態歷時分析與比較。

In mid-high-rise buildings, coupled wall systems (CWS) are widely adopted as effective structural components to enhance overall lateral stiffness. Due to practical requirements, including the accommodation of doors, windows, and elevator shafts, multi-panel shear walls were commonly formed. A CWS is composed of two or more independent structural walls interconnected with coupling beams.
To address the gap in understanding the seismic behavior coupled wall system beyond quasi-static hysteretic tests, a large-scale collaborative shaking table test has been conducted by a collaborative test of NCREE & QuakeCoRE. This large-scale experimental test aimed to investigate the structural response of combination of rigid and flexural lateral load resisting mechanisms.
This study focuses on the seismic response of coupling beams and were compared with the simulation results of OpenSees model. The proposed model for both individual coupling beams and coupled wall systems were validated against existing experimental results. The analytical model was incorporated with shear and slip behavior defined by modified compressive field theory (MCFT) and bond-slip behavior of reinforced concrete structure. The model could effectively capture cyclic behavior of coupling beams with varying designing parameters and the hysteretic response of a hybrid tested coupled wall system.
Since coupled wall systems are often integrated with moment resisting frames to form a dual system with openings, an extended simulation model for dual system without opening was proposed to support future dynamic analysis and comparative studies between different structural systems. This model was validated against the experimental result of E-Defense conducted in 2006.
