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。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.
