The non-linear strut-and-tie model (STM) can be used to analyse and predict the behaviour of reinforced concrete in disturbed regions. In this paper, a non-linear STM has been used to model the deformation capacity of conventionally reinforced intermediate-length coupling beams under cyclic and monotonic loads. The non-linear STM developed includes the contribution of concrete strength towards shear deformation and longitudinal bar slip through zero-length elements. The failure modes considered for the analysis were the crushing of the diagonal strut and diagonal tension (shear) failure of the beam. The model has been verified using various results of experimental works by researchers. It is found that the model could predict the behaviour and failure mode of the coupling beams rather accurately.

常规加固耦合梁的非线性拉杆-拉紧模型分析

非线性支撑杆系结模型(STM)可用于分析和预测受扰区域中钢筋混凝土的性能。在本文中,非线性STM已用于模拟常规加筋的中等长度耦合梁在循环和单调荷载下的变形能力。开发的非线性STM包括混凝土强度对剪切变形和通过零长度单元的纵向钢筋滑移的贡献。分析中考虑的破坏模式是对角撑杆的压扁和梁的对角拉伸(剪切)破坏。研究人员使用各种实验结果验证了该模型。发现该模型可以相当准确地预测耦合梁的行为和破坏模式。
