（中国建筑设计研究院，北京 100044）[摘要] 通过对腹板开洞尺寸超过规程限值的H型截面钢梁在不同限定条件下的ABAQUS有限元分析并综合对比无开洞及有开洞等情况下钢梁承载能力，阐明了被开洞钢梁的力学性能削弱问题，通过不同补强措施的对照，选取最安全合理的加固方案。[关键词] H型钢梁;腹板开洞;ABAQUS有限元分析;力学性能削弱分析;补强措施中图分类号：TU398.7 文献标识码：A 文章编号：1002-848X(2013)S1-0425-04作者简介：郭家旭，硕士研究生，助理工程师，guojx@cadg.cn。Capacity analysis of large openings in h section steel with FEMGuo Jiaxu, Luo Minjie, Huo Wenying(Abstract: Due to the problem floor clearance, openings which are over the limitation of code are applied in H section beams. In order to compare the different states of openings, FEM is generated to illustrate the capacity of beams. The states are fully demonstrated to optimise a more economical and safe plan compared with various measures of strengthening.Keywords: Welded section; openings in web; beyond limitation of code; FE modelling in ABAQUS; Capacity analysis; measures of strengthening
