摘要
本文通过有限元分析,研究了带墙板钢柱在墙板约束作用下的抗火承载力,也考察了钢柱截面温度不均匀分布对钢柱抗火承载力的影响。通过大量的有限元计算和参数分析,推导出了计算带墙板钢柱抗火承载力的简化设计方法。
Connected with a steel column at the flange of the column, the wall panels will give restraint to the column for buckling in the plane of the wall and thereby increase the load carrying capacity of the column at elevated temperature. A structural FE model is built for calculation of the fire-resistance of the column connected with wall panels. The effect of the uneven temperature's distribution in the section of the column is also considered in the simulation. Based on a parametric study, a simplified method for calculating the fire-resistance of such steel columns is provided.
