摘要
针对钢梁腹板不同开洞类型以及多种补强构造,采取MIDAS/Gen有限元建模分析了开洞局部应力的分布特点,指出菱形和圆形开洞应力较小以及补强措施减少了开洞边缘应力,同工程应用比较进一步证实了MIDAS/Gen在节点细部分析中的适用性。
According to various opening types and many reinforcement components of the steel beam,the paper adopts the MIDAS / Gen finite element modeling analysis of the distribution features of the local stress of the opening,points out the opening stress of the diamond and circular open stresses are smaller and the reinforcement measures can reduce the edge stress of the open,and proves by the further engineering application the adoptability of MIDAS / Gen in the connection joint analysis.
