摘要
为追求最低结构用钢量 ,我国相当一部分的门式刚架轻钢结构厂房采用了满应力设计。由于充分挖掘材料强度 ,使得结构安全储备相对偏低 ,往往荷载稍有增加 ,就得对原有结构进行加固设计。结合一工程实例 ,介绍门式刚架轻钢结构厂房的加固方法。
Steel structures have a good reliability.But if their material strength is overly used,the structures maybe have much lower repertory.Once special loading applied to them was increased,the structures must be strengthened.This paper discusses some methods to strengthen light-weight steel mill buildings of portal frames with an actual example.
