摘　　要：指出了在不能利用腹板屈曲后强度设计楔形梁时 ,按《门式刚架轻型房屋钢结构技术规程》(CECS 10 2∶2 0 0 2 )设计方法的保守性 。The article points out the conservatism in “Technical Specification for Steel Structure of One-story Light-weight Buildings with Portal Frames”(CECS 102∶2002),when it is used to design the tapered girder without using the post-buckling strength of web plates. Accurate calculation methods and some suggestions are also given in this paper.

关 键 词：门式刚架 腹板 楔形梁 高厚比 弹性设计
