【摘要】 我国地震区存在大量砌体结构,如何简单有效模拟这些砌体墙体的力学性能就成为分析的关键。本文基于多垂杆单元模型提出了一种水平剪切恢复力模型,并与试验进行对比。结果表明,本文建立的水平剪切恢复力模型可以有效地预计砌体墙体的抗震能力,可用于砌体结构抗震性能的评价。更多还原

【Abstract】 There are a large number of earthquake zone masonry structure existed in china,how to effectively and simply simulate the mechanical properties of these masonry wall has become analysis of key. In this paper,a horizontal shear of restoring force model based on vertical bar element model was proposed,and compared with the experiment. The results show that the horizontal shear of this restoring force model can be effectively estimated the seismic capacity of the masonry wall,can be used to evaluate the seismic performance of masonry structure.更多还原
