摘　　要：根据现行《钢结构设计规范》(GBJ1 7— 88)对一边自由一边与其他板件相连的板件的宽厚比限值来校核由H型钢剖分的T形截面腹板的宽厚比 ,会发现很多截面都不满足要求 ,这使得H型钢的推广应用非常不利 ,与国外技术先进国家的实际应用也不一致。为此 ,对T形截面腹板的宽厚比从板件相互约束的角度进行了研究 ,提出了相应的宽厚比限值计算公式 ,供规范修订和工程应用时参考。The width thickness ratio of T shaped section web,which is split by H shaped section steel members,is checked based on the current code Specification for steel structure (GBJ17—88). The results show that many T shaped sections cannot be satisfied with the regulation of local stability. This paper studies the width thickness ratio of T shaped section web concerned with the mutual restraint of slabs. The formula of limit of width thickness ratio is presented,which can be referred to revise the specification and apply in design.
