新型复合墙体开裂荷载的计算

Cracking Load Calculation of New-type Composite Wall

新型复合墙体开裂荷载是确定该结构体系墙体恢复力模型和损伤指数的重要参数。为了给该结构体系的设计和抗震理论提供依据,本文根据最小耗能原理推导出了该结构体系中填充砌块的开裂荷载计算公式,该式的计算结果与试验结果吻合较好,能完整描述填充砌块在剪压、剪摩下的破坏形态。

Cracking load of the new-type composite wall is an important parameter to determine restoring force model and damage index of the wall. Based on the least energy consumption principle, cracking load calculation formula of infilling masonry in the structure system is obtained. The formula result is in good agreement with experimental result. The failure model about shear-compression and shear-friction can be completely expressed with this formula. The method in the paper may provide an important reference to engineering design.
