摘要
本文建立了能反映砌体结构出平面破坏的三维空间刚体离散单元模型,并编制了计算机仿真程序,模拟了地震作用下砌体结构的倒塌反应,模拟结果和振动台试验结果比较,效果良好。
In this paper, the discrete element method （DEM）, is employed for the first time to perform masonry structural analysis under dynamic loading. A 3-dimentinal model is established to simulate the failure. The computer program developed can simulate the collapse responses of the masonry structures under earthquakes. The simulation results are in good agreement with the shaking table test data for a masonry structural model.
