THE LIMITATION OF WEB DEPTH-THICKNESS RATIO AND SHEAR RESISTANCE OF PORTAL FRAME TAPERED GIRDER
-
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》(CECS102∶2002)设计方法的保守性,同时给出了较精确的计算方法和供设计参考的建议。Abstract: 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.
