浅谈轻型门式刚架合理柱距的选择

Dissertation on Proper Column Distance Selection of Light-weight Portal Frame

在工业建筑中厂房柱距通常采用一定的模数,但在门式刚架轻型钢结构中,不合理的柱距模数会导致设计用钢量指标较高。在实际工程设计中通过结构设计软件PKPM进行结构分析比较,得出了在门式刚架轻型钢结构中造价最低的合理柱距:有吊车时一般为6～8m,无吊车时一般为8～9m。

Spacing module is often used in the layout of column system of industrial building.But in the portal frame light-weight steel structure industrial building,unsuitable module can cause too large design steel cost.In the actual design of the portal-rigid-frame light weight steel construction,it can be concluded,with the help of structural analysis software PKPM,that the economical column space is 6～8 m with a crane in the workshop,or 8～9 m without a crane.
