实腹式钢檩条设计需注意的几个问题

Discussion of Several Problems in the Design of Solid-bellied Purlins

钢结构设计中几乎每个项目都离不了檩条设计,檩条设计的风荷载取值、设计计算公式选取及多个规范选用是否合理准确,直接关系到结构安全和经济指标,文章通过研读相关多本规范,进行分析比较,阐明不同情况下的合理设计取用,对实腹檩条设计提供了较为清晰的设计思路。

Purlin design is indispensable to almost every project in steel structure design,wind load value of purlin design、whether the selection of design calculation formula and multiple specifications is reasonable and accurate,or not is related to structural safety and economic indicators.This paper is based on a study of several relevant specifications,analysis and comparison,explains the rational design utilization under different circumstances.It provides a clearer design idea for purlin with real belly.
