摘要:
為了研究灌漿套筒對裝配式混凝土梁柱節點抗震性能的影響,本文基于灌漿套筒試件單調拉伸試驗,采用多因素回歸分析,構建了灌漿套筒試件單向拉伸下的等效本構關系。并以該等效本構關系為依據,考慮了鋼筋混凝土之間的粘結滑移和新后澆混凝土界面的影響,利用ABAQUS有限元軟件,建立了灌漿套筒連接裝配式混凝土梁柱節點精細有限元模型,研究了灌漿套筒連接裝配式混凝土梁柱節點在低周反復作用荷載下的抗震性能。結果表明:節點主要塑性變形發生在梁柱相交界面,節點滯回曲線飽滿,節點核心區的耗能能力較好,有限元模擬結果與試驗結果中骨架曲線屈服荷載誤差為7.11%,峰值荷載誤差為6.88%,極限荷載誤差為3.76%,位移延性系數誤差為7.84%。有限元模型模擬結果與試驗結果吻合較好,表明采用等效灌漿套筒本構關系建立精細化灌漿套筒連接梁柱節點有限元模型是可行的。
