摘要
基于地震工程模拟开放系统OpenSees,提出了混凝土砌块砌体结构三维弹塑性地震反应数值分析方法,用带刚域的等效框架模型模拟混凝土砌块砌体结构,空间杆单元采用以力为基础的非线性梁、柱单元。数值模拟结果与试验结果较为吻合,验证了分析方法和计算模型的合理性。
A numerical analysis method for elastic-plastic seismic response of concrete block masonry is presented based on open system for earthquake engineering simulation system（OpenSees） .The method simulates concrete block masonry by using equivalent frame model with rigid offsets;the space beam-column elements are simulated by force based nonlinear beam-column elements. The numerical results keep in accordance with the experimental results,and this validates the correctness of the analysis method and calculation model.
