2007年普洱地震和2008年汤池地震中，“墙抬梁”式土木结构的震害主要表现在山墙倒塌，进而引起其他构件破坏。利用ANSYS软件，建立了“墙抬梁”式土木结构的三维有限元模型并进行时程分析。时程分析选取常见的Elcentro地震波和当地的普洱地震波进行计算，求解出连接处的最大位移差，找出了整体结构上的薄弱层，为今后土木结构的设计和抗震加固提供理论依据和支持。

Damage of adobe and wooden frame structure named "wall lift beam" was mainly shown in gable collapsing, and then caused damage of other components in Purer earthquake in 2007 and Tangchi earthquake in 2008. By using ANSYS general software, a three di- mensional model of adobe and wooden frame structure of the style "wall lift beam" is taken into account here for time history analysis. The maximum displacement differences at junction are obtained from time history analysis by selecting the common Elcentro seismic wave and the local Pu' er seismic wave for calculation. The weak points of whole structures are found out from the time history analysis eventually. All the above provide the theoretical basis and support for the design and seismic strengthening of adobe and wooden frame structure in the future.
