(苏州科技学院土木工程学院，苏州 215011)［摘要］在腹板利用屈曲后强度的条件下，推导了门式刚架中焊接H形截面构件设置横向加劲肋的计算式，给出了相应的计算数据表格。算例表明，应用所给出计算式，能较容易地解决门式刚架构件设置腹板加劲肋的问题。［关键词］门式刚架；焊接H形截面构件；腹板加劲肋；设置；计算公式Calculation and arrangement on the transverse stiffeners in structural members of gabled framesFang Tian(Institute of Civil Engineering, Suzhou University of Science and Technology, Suzhou 215011, China)Abstract:The calculation formulas for arranging transverse stiffeners in structural members with welded H-shaped cross sections in gabled frames were deduced under the condition of employing post-buckling shear strength of web plate, and the corresponding tables for calculated data were presented. Examples show that by using the calculating formulas, the problems of arranging web stiffeners in structural members of gabled frames can be easily solved.Keywords:gabled frame; welded H-shaped cross section; web stiffener; arrangement; calculating formula作者简介：方恬，硕士，副教授，Email:fangtian53@163.com。参考文献［1］CECS 102:2002门式刚架轻型房屋钢结构技术规程［S］.北京：中国计划出版社,2003.［2］魏潮文,弓晓芸,陈友泉. 轻型房屋钢结构应用技术手册［M］.北京:中国建筑工业出版社,2005.［3］陈绍蕃.钢结构(下册),房屋建筑钢结构设计［M］.北京:中国建筑工业出版社,2003.［4］《钢结构设计手册》编辑委员会. 钢结构设计手册(上册)［M］.3版.北京:中国建筑工业出版社,2004.
