浅谈钢结构冷换框架支撑的设计

On the Design of Steel Structure Cold Exchange Frame Support

在石化项目中,经常会遇到一些冷换框架,基本用于支承冷却设备、换热设备、卧式容器设备以及在框架顶层设置有空气冷却设备的钢结构框架。当运用结构设计软件PKPM进行抗震计算时,必须通过合理而又准确的结构形式,从而保证框架结构的强度和稳定。本文总结了已经做过的冷换框架的情况,对结构的方案设计、荷载输入、地震作用计算以及不同结构类型支撑的设计分析等几个方面进行了阐述。

In petrochemical projects,some cold exchange frames are often encountered,which are basically used to support cooling equipment,heat exchange equipment,horizontal vessel equipment and steel frame with air cooling equipment at the top of the frame.When the structural design software PKPM is used for seismic calculation,reasonable and accurate structural form must be adopted to ensure the strength and stability of the frame structure.This paper summarizes the situation of the cold exchange frame that has been done,and expounds the structural scheme design,load input,earthquake action calculation and design analysis of different structural types of supports.
