摘　　要：针对现有非线性动力分析程序的可视化和二次开发能力不强的特点,以SIMULINK为平台建立了层间剪切模型和平面杆系模型的非线性地震反应仿真模型,通过两个算例分析验证了模型的正确性,指出了基于SIMULINK的结构非线性地震反应仿真的优势。Since the existing programs of structural nonlinear seismic analysis have shortage of capability of visualization and exploration, simulations of nonlinear seismil response for the multi-storey shear-type model and the member model based on the SIMULINK are established in the paper, the results of two examples show that the simulation of structural nonlinear seismic responses based on SIMULINK is available and reliable.
