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。
Earthquakes happen frequently in villages and towns in our country, and the disaster caused by small earthquakes is the earthquake-resistant status in villages and towns. The villagers pay insufficient attention to earthquake fortification, the extensive construction of self-built houses and the disordered layout pose a threat to the safety of the towns and villages. In order to further study the seismic performance of brick and wood structure, by selecting a two-story brick and wood structure house, using finite element model ABAQUS software to carry out modal analysis and response spectrum analysis of the structure to obtain the basic dynamic characteristics of the structure, Under the structure of the response. After calculation and analysis, it explores the overall seismic performance and weak parts of brick and wood houses in villages and towns, which is of great practical significance to improve the safety of houses in villages and towns.
