村镇砖木结构房屋抗震性能研究

Study on seismic performance of brick and wood structure rural buildings

我国村镇地区地震发生频繁,小震致灾是村镇地区抗震现状。村民对抗震设防重视不够,自建房屋建造粗放、布局混乱等对村镇地区安全构成威胁。为了更深入研究砖木结构抗震性能,通过选取某二层砖木结构房屋,用ABAQUS软件建立有限元模型,对结构进行模态分析、反应谱分析,获得结构的基本动力特性、不同强度地震作用下结构的响应。经过计算分析,探究了村镇砖木结构房屋的整体抗震性能及薄弱部位,对提高村镇房屋安全性具有重要现实意义。

In order to further study the seismic performance of brick and wood structure, this article selects the typ-ical two-story brick and wood structure, and establishes finite element model by ABAQUS software. Through thestructure modal and response spectrum analysis, it gets the basic dynamic characteristics and structure responseunder different intensity ground motions. Through calculation and analysis, the paper explores the overall seismicperformance and weak parts of the brick and wood structure buildings, and it has very important practical signifi-cance to improve the rural housing security.
