单层厂房结构Pushover分析介绍与在Sap2000中的应用
|
摘要
Pushover分析方法是一种逐渐得到广泛应用的评价结构在罕遇地震作用下,抗震性能的简化方法,已被引入我国抗震规范所采用。本文介绍了Pushover分析的基本原理和实施Pushover分析的关键步骤以及Sap2000程序中Pushover方法的基本原理和方法,举出单层厂房Pushover分析实例,表明Sap2000程序可以较方便的实现单层厂房结构的Pushover分析,Pushover方法也可以对一般单厂结构的罕遇地震作用下的抗震性能做出合理的评价。
The pushover analysis has gradually become a widespread simplified method in the use of evaluating a structure's capacity in resisting a rare earthquake action,and our country code has introduced the method.This article refers to the basic principle of the pushover method,provides the key steps for implementing the pushover analysis,and also introduces the principles and methods in sap2000 for accomplishing pushover analysis.Take an example of one-story industrial building,which demonstrates that pushover analysis can be easily accomplished by using sap2000,and proves that the pushover analysis can be used in appraising the seismic resistant capacity of those normal one-story industrial buildings.
