摘要:
软土地基低层房屋砌体结构在中国应用较多,但它在地震中易损性较高,分析软土地基低层房屋砌体结构易损性,能够为地震预测任务与震后灾害评价提供帮助。为此,提出软土地基低层房屋砌体结构地震易损性分析方法,建立软土地基低层房屋砌体结构墙体模型并采用基于IDA的房屋砌体结构易损性运算方法,从差异开洞大小、差异开动数目、差异砂浆强度、差异层高四个方面分析软土地基低层房屋砌体结构地震易损性。软土地基低层房屋砌体结构地震易损性分析结果显示,软土地基低层房屋砌体结构墙体的开洞率较大,易损性较高；开洞数目少,易损性低；砂浆强度越小,易损性较高；层高越高,易损性越高。
Abstract:
The masonry structure of low-rise building on soft soil foundation is widely used in China,but it has high vulnerability in earthquake. Analyzing the vulnerability of masonry structure of low-rise building on soft soil foundation can provide help for earthquake prediction task and post earthquake disaster evaluation. Therefore,this paper puts forward the seismic vulnerability analysis method of low-rise building masonry structure on soft soil foundation,establishes the wall model of low-rise building masonry structure on soft soil foundation,and uses IDA based vulnerability calculation method of building masonry structure to analyze the seismic vulnerability of low-rise building masonry structure on soft soil foundation from four aspects:different opening size,different starting number,different mortar strength and different storey height. The results of seismic vulnerability analysis of masonry structure of low-rise building on soft soil foundation show that the opening rate of masonry structure wall of low-rise building on soft soil foundation is large and the vulnerability is high;the number of openings is small and the vulnerability is low,the smaller the mortar strength is,the higher the vulnerability is;the higher the floor height is,the higher the vulnerability is.
