相贯节点是钢管结构常用的节点形式,为评价不同加劲方式对大尺寸KT型相贯节点抗震性能的影响,使用有限元软件Ansys建立实体单元模型,分别对不设内部加劲肋、设置两个内部加劲肋、设置四个内部加劲肋情况下的相贯方钢管节点的滞回性能进行了有限元数值模拟分析,得到其在低周往复荷载作用下的滞回曲线及骨架曲线。通过比较各曲线异同,得出在竖腹杆下端设置加劲肋,节点的抗震性能最好。
相貫節點是鋼管結構常用的節點形式,為評價不同加勁方式對大呎吋KT型相貫節點抗震性能的影響,使用有限元軟件Ansys建立實體單元模型,分彆對不設內部加勁肋、設置兩箇內部加勁肋、設置四箇內部加勁肋情況下的相貫方鋼管節點的滯迴性能進行瞭有限元數值模擬分析,得到其在低週往複荷載作用下的滯迴麯線及骨架麯線。通過比較各麯線異同,得齣在豎腹桿下耑設置加勁肋,節點的抗震性能最好。

Tubular joint is a regular type of steel pipe structure .In order to evaluate the influence of seis-mic performance for KT joint with different internal stiffeners , the finite element software Ansys was used to build solid model and numerically analyze the hysteretic behavior .Without stiffeners , with two stiffeners and with four stiffeners were considered respectively , and hysteretic curve and skeleton curve under the low cyclic load were derived .Through comparing different curves , two stiffeners under the vertical member was advised .
