| 摘 要： | 为了观察不同梁、柱截面尺寸冷弯薄壁型钢钢板一螺栓节点静力性能的影响因素，采用AN—SYS软件对连接进行非线性有限元分析，研究3种梁柱腹板的节点螺栓间距、连接板厚度、腹板厚度和翼缘宽度等因素对其连接性能的影响．结果表明，梁柱腹板宽度、连接板厚度、梁柱腹板厚度是影响该连接节点静力性能的有效因素，而改变螺栓间距、梁柱翼缘宽度对节点的初始刚度和极限承载力的影响都不明显．给出了3种截面形式节点的设计建议，并对节点滞回性能进行了初步探讨，提出了滞回性能指标分析结论．

| Abstract: | The ANSYS mftware is used to investigate the influential factors of the static behavior of gusset plate-bolted connection. The influential factors of the connections of three kinds of width of beam-column web were studied, including bolt pitch, the thickness of gusset plate, and the thickness of web and the width of flange and so on. It is found that the width of beam-column web the thickness of gusset plate, the thickness of web are highly effective factors for the static behavior, while the bolt pitch and the width of flange do not affect the initial stiffness and the ultimate bearing capacity of the joints. Finally, design proposals of three sections form connections are demonstrated, the dynamic per- formance of three kinds of recommended connections have been preliminarily studied in this paper. |
