摘要
广州新白云机杨航站楼屋盖采用两个帽形冷弯型钢通过翼边板上纵向点焊形成组合箱形截面受弯构件 .根据组合截面在均布荷载作用下的简支梁跨中截面抗弯、支座截面抗剪的受力分析 ,给出了组合截面翼边板上焊点间距的取值 。
A flexural member is composed of a couple cold formed steel hat sections by spot welding on the longitudinal lips used in the Guangzhou new Baiyun Airport Buildings.The spacings of the spot welds for simple beam under uniform loads is presented by analyzing the bending of middle span and the shearing of supported sections.The spacings of spot welds presented here can be used to the project.
