为深入研究热轧型钢拼合柱的受力性能,采用ABAQUS建立了10个有限元计算模型,分析了长细比、螺栓间距对拼合柱轴压性能的影响.结果表明拼合柱的极限承载力均略低于同截面整柱,当螺栓间距增大到80i时,拼合柱承载力下降到整柱的80%,长细比和螺栓间距对拼合柱承载力影响显著,随着长细比和螺栓间距增加拼合柱极限承载力逐渐降低.
RESEARCH ON AXIAL COMPRESSION PERFORMANCE OF HOT-ROLLED STEEL COMPOSITE COLUMNS BASED ON ABAQUS
Ten finite element models are established by using ABAQUS to investigate the load-bearing performance of hot-rolled composite columns with different cross-sectional forms. The influence of aspect ratio and bolt spacing on the axial compression performance of the composite columns is analyzed. The results show that the ultimate bear-ing capacity of the assembled column is slightly lower than that of the entire column with the same cross-section. When the bolt spacing increases to 80i,the bearing capacity of the assembled column decreases to 80%of the entire column. The slenderness ratio and bolt spacing have a significant impact on the bearing capacity of the assembled column,and the ultimate bearing capacity of the assembled column gradually decreases with the increase of the slen-derness ratio and bolt spacing.
