摘要
根据弹性稳定理论原理研究了钢结构构件在高温环境下的静力特性问题,导出了高温下杆件的静力稳定临界力的计算式,并讨论了温度、长细比、构件截面形式、材料特性等因素对杆件静力稳定临界力的影响,探讨了在实际工程中如何减小结构失稳的问题,可为钢结构抗火设计提供参考。
The analysis of force of slab super-structure under high temperature are studied by elasticity stability theory. The calculating formulas for critical force of whist force stability of structure under high temperature are conducted. The effects of factors such as fire temperature,section forms of members,ratio of length and thin,material character and depth of concrete cover etc on the critical force of whist force stability are studied. The problems how to apply in pratical engineering are discussed.
