Xinjiang is a place which has a lot of earthquake of our country, not only are the earthquake activities high-frequency,strong, but also widespread. For hundreds of years, Xinjiang has had the earthquake with More than 6 grades for 102 times, More than 7 grades for 12 times, including two great earthquakes for 8 grades, tens of thousands of the buildings collapsed, directly endanger the safety of the people's lives and property, as such, our country immediately call on to carry out the Aseismic Dwelling House Project in Urban and Rural Areas of Xinjiang, took corresponding measures to alter the buildings, in order to meet the requirement of aseismic design of the houses, it has important significance for protecting the safety of the people's lives and property and passing the national history culture.This paper according to the wide-ranging survey, put forward the aseismic dwelling houses which conform to the practical situation of Kashi, Sinkiang, China, this paper will choose the aseismic dwelling houses which base on stone and wood structure. According to the shaking table test of these house, analyzing the damages to the appearance and the mechanism of the structure, coming at the structure dynamic characteristics , earthquake reflection and the earthquake-resistant performance. Drawing the preliminary conclusions of trial.At the same time, this paper use the infinite analysis program ANSYS, analyzing stone and wood Structure by analysis of plastic history, according to the analysis of this model's numerical results, coming at the natural frequency of vibration of the structure,stress,movement nephogram and time history analysis graph in every kind of working condition. Thus can be drawn from stone and wood structure types of housing good seismic performance, to meet the basic intensity to 8 degrees (0.2 g) in the seismic fortification requirements. Housing and construction procedures simple, low-cost, superior performance and to meet their living conditions, it is suitable for use.
