Pushover分析在框架结构加固中的应用

application of pushover analysis to framework structure strengthening

首先介绍了Pushover分析的基本原理和一般的分析步骤。然后结合工程实例对其进行了具体说明,通过对实际工程设定参数、构建数据模型、建立Pushover工况,并对其进行静力弹塑性分析(Pushover分析),评估了该建筑物的抗震性能。当抗震性能不能满足大震需求性能目标时,需对其进行加固。这里采用钢板进行加固。

This paper firstly introduces the basic principle of pushover analysis and general steps of analysis,and then uses the actual construction example to illustrate its application.The paper aims to evaluate the anti-seismic property of the framework structure building through setting parameters,building data model and establishing pushover conditions,and then does the static elastoplastic analysis.When the anti-seismic property of the building can not meet the demand,the strengthening is needed.This paper employs the steel plate for reinforcement due to its advantages.
