西北农居震害构成及抗震性能综合影响因素分析

Seismic Damage Composition of Rural Houses in Northwest China and Factors Influencing Their Seismic Performance

整理西北地区部分地震的震害资料,对西北五省的主要农居进行震害总结,分析不同结构农居震害和抗震性能,发现不同结构的抗震性能差别较大,并针对不同结构提出相应的防震减灾措施。从地震动特性、场地和地基基础、结构的自身特性等方面分析影响农居民房的抗震能力,并根据西北农居震害特点给出了防震减灾方面的一些建议。

This paper summarizes the seismic damage data of some earthquakes in northwest China and the earthquake damage of rural houses in northwest China.Through an analysis of the seismic damage and seismic performance of different structures of rural houses,the seismic performances of different structures were found to be significantly different.Meanwhile,we propose the corresponding aseismic measures for different structures.The seismic capacity of rural houses was analyzed from the aspects of ground-motion characteristics,site and foundation,and structural characteristics.Then according to the earthquake damage characteristics of rural houses in northwest China,some recommendations on earthquake prevention and disaster reduction are presented.
