| 摘 要： | 自从Pushover分析法被引入我国以来,就受到了广大结构设计人员的关注,这种方法适合被用来分析结构静力非线性特性.在EATBS2013程序中,Pushover法主要是基于国外规范提及的FEMA440法,拟利用ETABS2013有限元分析软件,建立经过程序自动优化截面后的三维K型偏心支撑组合高强钢框架模型,分析其在静力作用下弹塑性阶段的内力变形及塑性铰分布情况.

Pushover Analysis of High Strength Steel Frame with Eccentric Brace Based ETABS |

| Abstract: | Since the introduction of Pushover analysis into China,this method has been paid attention by most of structural designers.This method can be used to analyze the static nonlinear characteristics of structures.In the EATBS2013 program,Pushover method is mainly based on the FEMA440 method mentioned in the foreign specification.In this paper,the ETABS2013 finite element analysis software is used to establish the three-dimensional model of eccentrically braced composite high-strength steel frame after the program automatically optimizing the cross-section,and its internal force deformation ,and the plastic hinge distribution under static load in elastic-plastic stage are analyzed. |
