摘要

立足于抗震性能化设计中性态水准划分不明确的问题,依据所建立的砌体损伤本构方程,建立了不同窗洞口尺寸和不同构造措施的砌体房屋有限元模型,对模型进行Pushover分析,采用了基本损伤参数和整体损伤参数,对结构在地震作用下的刚度变化和损伤发展进行定量描述,并引入了综合评价系数对性态水准进行深入划分和评价.
Based on the unclear division of the performance levels,finite element models of masonry buildings with windows of different sizes and different structural measures,according to damage constitutive equation of masonry in strain space and damage evolution equation,are built,which are analyzed by the Pushover analysis method.Stiffness change and damage evolution of masonry buildings under earthquake action are quantitatively described by the basic damage index and holistic damage index.In order to show their joint action on seismic performance of masonry buildings,the comprehensive evaluation coefficient is suggested to divide and evaluate performance levels of masonry buildings,which can evaluate overall seismic behavior of masonry buildings.
