焊接H形截面门式钢刚果联合厂房温度区段长度限值探讨

Limit length Analysis of the Temperature Divisions of JointFactory Building with Welded H-Section Steel Portal Frames

本文通过对厂房的温度效应的分析，提出了焊接H形截面门式钢刚架联合厂房温度区段长度决定的主要原则及联合厂房温度区段长度限值通过反算来确定的方法。工程实践证明，结构安全度可靠，且能满足使用要求。

Based on the analysis of temperature effects of factory buildings, this paper presents the mainPrinciples of determining the length of temperature divisions of joint factory buildings with weldedH-section steel portal frames and the approach of deciding the limit length of joint factory buildingbough back computation. It is proved by engineering practice that the safety and reliability of thestructure designed by this method are enough to meet the reqUirements for usage.
