摘要
波浪腹板工形构件作为受弯构件具有较高的承载效率。波浪腹板工形构件作为轴心受压构件使用,在截面合理设计条件下也仍不失为一种性能良好的构件。通过理论和数值分析,对波浪腹板轴心受压构件的稳定性设计理论进行研究,提出其稳定承载力的计算方法;制作了两个试件进行轴压试验研究,并与有限元分析结果进行对比。同时比较平腹板与波浪腹板受压构件的经济性,说明在构件绕强轴失稳破坏的情况下,减小波浪腹板的厚度而增大其高度可获得较大的承载力。
A H-shaped beam with a sinusoidal corrugated web has a high load-carrying efficiency under bending, but it is still verified to be highly efficient as an axial loaded column by a rational design for the section. This paper focused on the buckling behavior and corresponding design formula of the sinusoidal corrugated web column loaded axially. Two specimens axially loaded were tested, and the obtained test results were consistent with those of finite shell element analysis. Additionally, a comparison of load-carrying efficiency and design economics between the fiat and corrugated web columns was. also made.
