In recent decades, different macro-models have been proposed for simulating the behaviour of concrete shear walls because of their significant role in the seismic performance of urban buildings. The ability of Timoshenko's beam theory to evaluate the behaviour of slender and moderate-aspect-ratio concrete shear walls was evaluated in this work. For this purpose, a non-linear displacement-based Timoshenko fibre element was first added to OpenSees software. A new constitutive model based on modified compression field theory was used for the stress–strain relationship of the materials. To validate the element and the materials used, the results of the numerical model were compared with a set of laboratory tests of concrete shear walls subjected to cyclic and seismic loads (shaking table tests). Evaluation of the numerical model and the experimental results revealed that the analysis procedure used to model the reinforced concrete walls predicted their overall and local responses with acceptable accuracy. It can thus be used as a reliable tool for the analysis of slender and moderate-aspect-ratio concrete shear walls.

使用 Timoshenko 理论预测钢筋混凝土墙响应的数值建模策略

近几十年来，由于混凝土剪力墙在城市建筑抗震性能中的重要作用，人们提出了不同的宏观模型来模拟混凝土剪力墙的行为。在这项工作中评估了 Timoshenko 的梁理论评估细长和中等纵横比混凝土剪力墙行为的能力。为此，首先将基于非线性位移的 Timoshenko 纤维元件添加到 OpenSees 软件中。基于修正压缩场理论的新本构模型用于材料的应力-应变关系。为了验证所使用的元素和材料，将数值模型的结果与一组承受循环和地震荷载的混凝土剪力墙的实验室试验（振动台试验）进行了比较。对数值模型和实验结果的评估表明，用于模拟钢筋混凝土墙的分析程序以可接受的精度预测了它们的整体和局部响应。因此，它可以用作分析细长和中等纵横比混凝土剪力墙的可靠工具。
