【摘要】 高频焊接矩形管柱生产效率高,抗扭性能好,平面外刚度好,并且根据需要内部可以充填混凝土, 提高抵抗局部屈曲的能力,比目前的采用焊接(变截面)H型钢的轻钢厂房有更好的经济性。为提高梁柱连接节点的承载力、减小节点变形,提出了箱形柱柱顶与梁上翼缘齐平,槽钢与梁端板等厚,槽钢向上伸出长度以满足安装一排高强螺栓的要求,并设置三角形加劲肋与柱顶盖板和槽钢焊接,箱形柱顶和槽钢内面满焊的节点形式,分析表明这种节点有很高的刚度和强度,能很好地满足刚性连接的要求。更多还原

【Abstract】 High-frequency welded rectangular tube column has high production efficiency, high torsional and out-of-plane stiffness. Sometimes concrete may be filled into the tube to improve its capacity and behavior against local buckling. High-frequency welded rectangular tube column is more economic than the current welded H-section steel (variable cross-section) light industrial building . In order to increase bearing capacity of beam-to-column connection and reduce joint deformation, a new joint detail is proposed, of which column head was flushed with beam upper flange, partial column web was welded with U - steel, and extended U - steel has stiffener. Calculation shows that this connection has very high joint stiffness and strength, and may meet requirements of a rigid connection in terms of its stiffness and capacity.更多还原
