污染土清挖治理项目的大空间轻钢屋面厂房钢结构设计实例分析

Case Analysis on Steel Structure Design of Large-Space Light-Steel Roof Building in Contaminated Soil Dredging and Excavation Management Project

以大跨度单层工业厂房的实际工程为例,根据有关技术资料和现行规范要求并运用建筑结构专业设计软件,对该厂房进行三维空间分析。本文针对本钢结构单层厂房总结了抗震设计中构件长细比、板件宽厚比的控制方法,计算的结果表明大跨度厂房需要考虑空间效应,同时钢结构节点的承载力验算也十分必要。

Taking the actual project of a large-span single-storey industrial building as an example,according to the relevant technical data and the requirements of the current code,using the professional design software of the building structure,the three-dimensional space analysis of this building is carried out.In this paper,the control methods of component slenderness ratio and plate width-thickness ratio in seismic design are summarized for the steel structure single-storey building,and the calculated results show that the spatial effect needs to be considered for the large-span building,and the bearing capacity calculation of steel structure joint is also very necessary.
