摘要
采用数值计算方法分析了高温下钢结构平面和空间压弯构件的整体稳定问题,并编制了计算机程序.分析中可以考虑构件截面不均匀温度分布以及随温度而变的材料力学性能等因素的影响.该方法可用来计算钢结构压弯构件在一定温度状态下的稳定权限承载力或一定荷载状态下构件的温度极限值.
The stability behavior of steel beam columns at high temperatures is studied numerically and a computer program is developed in this paper. Effect of the nonuniform distribution of temperature over theelement section and temperature dependent meterial properties are both involved.Based on the analysis, theload-bearing capecity of steel columns a specified state or the critical temperature at a specifiedload level can be calculated.
