木结构房屋的抗震性能及保护措施

Earthquake-resistance Performance and Protective Measures of the Timber Structural Buildings

从木结构房屋的构造形式特点出发 ,研究了不同烈度地震作用下木结构房屋的震害特点 ,并以西安回民保护区典型木结构房屋为例 ,按 8度抗震设防考虑 ,分别对木结构房屋的纵向、横向进行了内力分析和承载力计算 ,并利用通用有限元程序ANSYS对木结构房屋进行了三维空间分析。通过平面与空间的计算 ,指出木结构房屋抗震存在的问题 。

Through the structural styles of the historic timber structural building, this paper discusses the earthquake disaster characteristics of the timber structural building under the different seismic intensity. Taking the typical timber structural building in Xi'an as an example, it analyzes the internal forces and calculates the bearing capacity to the classic timber structural building in the both length and cross direction. It uses the finite element software ANSYS to build three-dimensional model and make analysis. This paper also discusses the relevant earthquake-resistance measures to protect the historic buildings.
