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。
Through the ABAQUS finite element analysis of H-section steel beams with web openings exceeding the limits of the rules, under different conditions, the load-carrying capacity of the steel beams without openings and open holes is compared, The mechanical properties of the hole steel beam are weakened. Through the comparison of different reinforcing measures, the most safe and reasonable reinforcement plan is selected.
