摘要

本文进行了6个方形钢管混凝土柱与钢梁连接节点足尺模型的拟静力试验,包括穿芯螺栓-加劲端板连接(SEP)节点、缀板焊接连接(SPW)节点与常规栓焊(NBW)节点三种。比较了这三种连接节点在不同轴压比下的滞回性能、强度与刚度退化、延性性能、耗能能力以及破坏特征。结果显示:破坏大多发生在节点连接部位或钢梁局部屈曲或开裂,SEP节点与SPW节点的整体抗震性能要优于常规栓焊节点。
A quasi static experimental research program is presented in this paper. Six full size concrete filled square steel tube column to steel beam connection specimens were tested under low cycle reversed loading at the ends of beams, including three types of connections, namely side plate welding (SPW) connection, stiffened end plate (SEP) connection, and the normal bolt welding (NBW) connection. The hysteretic behavior, degradations of strength and stiffness, ductility and energy dissipations, the modes of failure of the SPW and SEP connections were compared with those of the NBW connection under different axial compression ratios. Based on test results, possible failure modes of these connections were identified as joint failure or steel beam cracking or buckling. It can be concluded that the seismic behavior of the SPW connection and the SEP connection are better than that of the NBW connection.
