基于Pushover方法的某中学框架校舍抗震鉴定
|
摘要
Pushover分析方法是一种基于位移的静力弹塑性分析方法,可以快速地对结构的抗震性能进行评估,近几年在国内外得到了广泛的重视和应用。首先采用我国现行抗震鉴定标准中的两级鉴定方法对一中学框架结构教学楼进行了抗震鉴定,同时,采用Pushover分析方法对教学楼的抗震性能进行了分析,对其进行了基于性能的抗震鉴定,考察了结构在不同水准地震作用下的响应,进行了罕遇地震作用下结构的弹塑性变形验算,判断结构能否满足大震下不倒塌的设防要求。
The pushover analysis is a static elasto-plastic analysis method based on the displacement.It can help quickly evaluate building structures and it is widely used in China.In this paper,a school building with the frame structure was evaluated by using the two-level method provided by the current standard for seismic appraisal of buildings in China.Pushover analyses were performed and responses of this school structure under different seismic levels were obtained.The elasto-plastic deformation of this building under rare earthquake was checked to avoid collapse.
