Abstract

This research intends to investigate behaviour of composite cold-formed steel joint numerically through finite element analysis by using ABAQUS and theoretically by referring to BS 5950-1:2000 and Green book P213 “Joint in Steel Construction-Composite Connection”. A composite joint is modelled by combination of composite beam and steel column with connection of HRS gusset plate and M12 bolts. The significant failure mode is local buckling in CFS column web which similar in experimental study, FEM numerical simulation and theoretical component calculation. The behaviour of the cold-formed steel composite joint will be expressed in moment-rotational and load-deflection relationship to determine the initial rotational stiffness and ultimate moment resistance. The findings from numerical and theoretical investigations are compared with the full-scale experimental study in three different thicknesses of gusset plate. A correlation in stiffness ratio and strength ratio are obtained in the range of 1.76 to 2.25, and 1.00 to 1.60 respectively indicating that the numerical modelling tends to underpredict the behaviour of the composite structures.

轻型混凝土与冷弯型钢组合节点的数值与理论研究

本研究旨在通过ABAQUS有限元分析，并参考BS 5950-1:2000和绿皮书P213《钢结构复合连接中的节点》，从理论上对冷弯型钢复合节点的性能进行数值研究。采用HRS节点板和M12螺栓连接的组合梁和钢柱组合，建立了组合节点模型。在试验研究、有限元数值模拟和理论构件计算中，CFS柱腹板的局部屈曲是其主要失效模式。冷弯型钢组合节点的性能将用力矩-转动和荷载-挠度关系表示，以确定初始转动刚度和极限力矩阻力。将数值和理论研究结果与三种不同厚度节点板的全尺寸实验研究结果进行了比较。刚度比和强度比的相关性分别在1.76至2.25和1.00至1.60的范围内，表明数值模型往往低估了复合材料结构的性能。
