摘要
地裂缝是严重影响我国人类生活、生产建设的主要地质灾害之一,是一种独特的地质灾害,近年来已引起人们的关注,它广泛分布于全国许多地方。框架结构是一种广泛使用的结构形式。由于人类活动或地质构造运动形成地裂缝,进而造成房屋开裂或倾斜。该文针对位于抗震设防区的框架结构房屋,分别用底部剪力法和PKPM静力分析法,来定量研究在地裂缝影响下框架结构的抗震性能,为双重灾害影响下结构抗震鉴定加固提供依据。
As one of the main geological disasters, ground fissure is seriously affecting people＇s life, production and construction in China. Ground fissure is a kind of unique geological disaster in recent years. It is widely distributed. Frame structure is a widely used structure form. Because human activity or geological tectonic movement forms ground fissure, the ground fissure causes housing cracking or tilt. The paper conducts the quantitative research on seismic performance of structure which is in seismic area under the influence of the ground fissures with two methods： the bottom shear method and PKPM. It can provide the basis for aseismatic appraisal of the structure under the double disasters.
