对门式刚架柱截面设计的分析

通过理论推导和工程设计实例,给出钢柱断面设计中合理的高宽比值及适用范围。有效解决了钢结构设计中普遍存在的问题。即:构件的强度应力和稳定应力相差较大,使构件在强度还很富裕时就因失稳而破坏,对钢结构设计具有指导作用。

By the theory-consequence and the engineering design case,this paper conludes the reasonable ratio of hight and width,apply-extension which is in the design of the steel pole section.It solved the common question which is in the design of steel structures.That is when the difference of the intension-stress and stabilization-stress is bigger,the component is wrecked for lose- stabilization.The conclusion of this paper offers any experience for the design of steel structures.
