摘要
我国现行钢结构设计规范及规程中对连续檩条的设计存在很多不足。本文探讨冷弯型钢连续檩条的最不利荷载分布形式、搭接长度、搭接处简化模型。结合加拿大、美国和中国规范,提出冷弯型钢连续檩条最不利荷载分布形式。使冷弯型钢连续檩条设计更为经济、合理。
Three is a number of things inadequate in the design of the continuous purlin stipulated in China＇s current code and rule on steel structure design. This article explores cold-formed steel continuespurlin for the most disadvantaged form of the load distribution, lap length, simplified model of the lap. Combining with Canada, the United States and China norms, proposes the most disadvantaged form of continues purlin load distribution for cold-formed steel,in order to enable cold-formed steel continues purlin design of more economic and rational.
