摘　　要：运用Abaqus软件,依据《钢结构设计标准》和《高层建筑钢结构技术规程》相关条文,对建立的两组(共五个)有限元模型进行分析,得出荷载-跨中位移曲线和Mises应力云图,从而揭示开孔钢梁在采用加设套管、双侧环形板、纵横向加劲肋这三种加固方式之后,其对腹板开孔钢梁的极限承载力和塑性发展范围方面的有利影响。According to the relevant provisions of“Design Standard for Steel Structures”and“Technical Specification for Steel Structures of High-rise Buildings”,two groups(five in total)of finite element models were analyzed by Abaqus,and the load-mid-span displacement curve and Mises stress nephogram were obtained.It is revealed that the three strengthening methods,namely,adding casing,double-sided annular plates,and longitudinal and transverse stiffeners,have favorable effects on the ultimate bearing capacity and plastic development range of steel beams with web holes.
