摘要
用可移动元胞自动机(MCA)数值模拟方法,建立有窗洞的砌体结构模型,并对其在不同烈度地震作用下的破坏过程进行了数值模拟,模拟结果与实际发生的地震破坏情况相符,给出了砌体顶层加速度峰值和均值与地面加速度峰值和均值的关系,对实际工程有一定的指导作用.
The MCA method is used to construct window-bearing masonry structure model, and the numerical simulation on destructive process under different intensity earthquake effect is carried out. The simulation results are consistent with the destruction condition of practical earthquake. The relation between masonry envelope top floor peak acceleration and average values, ground peak acceleration and average values are acquired. It has instructive significance in practice.
