门式刚架轻型房屋钢结构设计施工中的常见问题

Common Problems in Steel Structure Design and Construction of Portal Frame Light House

由于门式刚架结构已在最近数年获得广泛应用,并存在较好的发展前景。但由于这种结构类型对钢结构技术有较大的依赖性,因此在工程设计上存在着许多的技术要求标准问题。本文主要从屋面结构活荷载的取值范围、斜梁尺寸取值范围、构件挠度、构造型式与布局、屋盖的防风性措施、防腐防火能力等方面,研究了门式刚架与轻型房屋钢构件相关设计问题。

The portal frame structure has been widely used in recent years and has a good development prospect.However,due to the large dependence of this structure type on steel structure technology,there are many technical requirements and standard problems in engineering design.In this paper,the design problems of portal frame and light house steel components are mainly studied from the aspects of the value range of roof structure live load,the value range of inclined beam size,the deflection of components,the structural type and layout,the wind protection measures of the roof,and the anti-corrosion and fire prevention ability.
