典型框架式学校建筑的抗震性能分析

The Seismic Analysis of Typical Frame Structure of School Buildings

本文在研究汶川地震灾区学校建筑震害的基础上,探讨了中小学校典型框架结构即外廊悬挑式单跨框架结构的抗震性能。基于静力非线性方法,用ETABS对典型框架结构进行弹塑性分析,对不同水准下结构的出铰顺序,出铰数量,侧向位移等进行对比,得出相应的抗震性能评价,本文还对该框架结构的薄弱部位进行分析,提出加固改造的相关建议。本文的研究工作对提高学校建筑的抗震能力具有实用价值。

Based on the damage analysis of school buildings during Wenchuan Earthquake,the seismic capacity of the typical frame structure of school buildings was discussed.By means of ETABS software,the elasto-plastic analysis of typical frame structure was carried out to study the order of plastic hinges,the amount of plastic hinges and the lateral displacement etc.In order to improve the seismic capacity,some suggestions were given for the retrofit of old school buildings.This research is very valuable to enhance the seismic capacity of school buildings.
