Under strong earthquakes, reinforced concrete (RC) walls in high-rise buildings, particularly in wall piers that form part of a coupled or core wall system, may experience coupled axial tension–flexure loading. In this study, a detailed finite element model was developed in VecTor2 to provide an effective tool for the further investigation of the seismic behaviour of RC walls subjected to axial tension and cyclic lateral loading. The model was verified using experimental data from recent RC wall tests under axial tension and cyclic lateral loading, and results showed that the model can accurately capture the overall response of RC walls. Additional analyses were conducted using the developed model to investigate the effect of key design parameters on the peak strength, ultimate deformation capacity and plastic hinge length of RC walls under axial tension and cyclic lateral loading. On the basis of the analysis results, useful information were provided when designing or assessing the seismic behaviour of RC slender walls under coupled axial tension–flexure loading.

在强地震下，高层建筑中的钢筋混凝土 (RC) 墙，特别是构成耦合或核心墙系统一部分的墙墩中，可能会承受耦合的轴向拉弯载荷。在这项研究中，在 VecTor2 中开发了一个详细的有限元模型，为进一步研究 RC 墙在轴向拉力和循环横向载荷下的抗震性能提供了有效的工具。该模型使用最近在轴向拉力和循环横向载荷下的 RC 墙测试的实验数据进行了验证，结果表明该模型可以准确地捕捉 RC 墙的整体响应。使用开发的模型进行了额外的分析，以研究关键设计参数对峰值强度的影响，钢筋混凝土墙在轴向拉力和循环横向荷载作用下的极限变形能力和塑性铰长度。在分析结果的基础上，为设计或评估 RC 细长墙在轴向拉弯耦合载荷下的抗震性能提供了有用的信息。
