预测面外荷载下砌体墙板破坏模式的CA模型

CA model for predicting failure pattern of laterally loaded masonry wall panel

基于典型墙板试验记录,提出了应用细胞自动机技术直接预测面外均布荷载下砌体墙板破坏模式的方法,其中一个传递函数被用来模拟边界效应向墙板内各个区域的传递和效应,由此产生了基础墙板和新墙板内各个区域的状态值,进而应用所建议的准则匹配两墙板内的类似区域,最后以两墙板的类似区域和基础墙板的试验破坏模式为依据,鉴别出新墙板的破坏区域,预测出新墙板的接近试验结果的破坏模式.

This paper introduces a technique for directly predicting the failure patterns of laterally loaded masonry panels, based on the results of a few existing standard masonry panels tested in the laboratory and cellular automata. In this technique, the proposed transition function is used to propagate boundary effect into zones within the panel and then the state values of the zones are derived. Furthermore, the corresponding criteria is proposed to implement the cellular automata （CA） technique which matches similar zones between two panels. Finally, the failure patterns of unseen panels are directly predicted by matching cracking zones on similar zones.
