摘　　要：基于高温环境下钢构件的受力特点,根据压弯构件的平衡方程,导出了不同横向荷载形式下钢构件的稳定承载力计算公式,分析了横向荷载及火灾参数对钢构件稳定承载力的影响,提出了在实际工程中采取的一些相应措施。The article is based on being pressed properties of steel member under high temperature condition. According to the balance equations of bearing and curving load, it led the computes formula of stable bearing capacity in form of different transverse loads＇ steel structure. The influence of different load and fire parameter on bear the weight of stability of steel bar were analyzed. Some suggestions were given for reducing the temperature arise of steel bar in practical engineering.

关 键 词：高温环境 压弯杆件 横向荷载 稳定承载力
