【摘要】 在对西北地区农村民房实地调研的基础上,根据承重结构、建筑材料和工艺的不同,将其划归为生土墙体承重房屋、砖砌墙体承重房屋、木构架承重房屋和混合承重房屋。研究表明,不同类型房屋分布具有明显的区域性和年代特征,抗震性能差异较大,但均存在不同程度的地震安全问题;提高西北地区农村民房的抗震能力,需要加快实施农居地震安全工程,加快危房的拆除重建和抗震加固工作,开展民房抗震技术研究,推广抗震农居。更多还原

【Abstract】 Based on investigations to rural buildings in northwest China,they are classified to raw-wall bearing house,brick-wall bearing house,timber-frame bearing house and mixed-construction bearing house by the difference of load-bearing structure,building materials and technology.The paper shows that rural houses have obviously regional characteristics and building age.It also shows great differences of anti-seismic performance and security problems more or less.For improving anti-seismic level of rural houses,it needs to accelerate seismic security projects of rural buildings,dismantlement and reconstruction of dangerous houses,to launch research of anti-seismic technology,and to popularize anti-seismic rural houses.更多还原
