交叉支撑对钢框架结构抗震性能影响和设计

Influence and Design of Cross Bracing on Seismic Performance of Steel Frame Structures

为有效地解决变电站钢框架结构存在的凹凸不规则、楼板局部不连续、扭转不规则等问题,文中提出一套行之有效的交叉支撑设计方案,并以某地区220kV变电站为研究对象,全面分析交叉支撑对变电站钢框架结构抗震性能影响,完成对交叉支撑的科学设计。

In order to effectively solve the problems of concave and convex irregularities,local discontinuity of floor and torsion irregularities in steel frame structure of substation,a set of effective cross-support design scheme is proposed.In this paper,a 220kV substation in a region as the research object,in a comprehensive analysis of the cross-support on the seismic performance of steel frame structure substation,complete the scientific design of cross-support.
