摘要
《钢结构设计规范》(GB50017-2003)对组合钢梁腹板的局部稳定作了较大改动,通过建立有限元模型并考虑多种几何参数及应力组合,对腹板的局部稳定进行了深入的研究,对新规范中梁腹板区格在复合应力作用下的局部屈曲相关公式进行了验证,重点分析了此相关公式的安全度。
In the revised code (GB50017-2003),a greater change in the computational formula for local stability of beam web was made and this problem is deeply analyzed and studied,considering the effects of various geometric parameters and stress combinations on buckling critical stress of webThe revised local buckling correlative formula for transverse and longitudinal stiffened web panels under combined stresses is analyzed and verified by finite element methodrelative safety degree of the correlative formula is examined emphatically
