摘要
对轴心受压T形钢构件中翼缘和腹板的相关屈曲做了理论分析 ,在弹塑性阶段采用有效模量来综合考虑残余应力、初始弯曲、材料非线性等的影响 ,并推导了翼缘和腹板的宽厚比限值公式 ,最后将建议公式与我国现行规范GEJ1 8-
The interactive buckling of flanges and web on T section members under axial compression is analyzed theoretically. Effective modulus is used to consider factors such as residual stress, initial bending, and material nonlinear in the elastoplastic stage. Limitations of panels' selenderness are derived. The relevant items of the current specification GBJ 17-88 have been compared with recommended formulas at the end of this paper.
