3. the performance of staggered joints is similar to ordinary joints ', not only about the plump of hysteresis curves, energy dissipation, but also the time, the rapidity of shear resistance decrease and the degree of joints stiffness degradation. only the displacement ductility coefficient in staggered joints is little smaller than in ordinary joints
錯層節點的抗震性能比普通節點的抗震性能基本差不多，不管是從梁端滯回曲線的飽滿程度、耗能系數，還是從節點承載力降低的早晚、快慢、節點剛度退化的程度上來說，都是這樣，唯有錯層節點的位移延性系數，要比普通節點的稍差一些。 -
Meanwhile, the influence of overlapping area on the beam foundation is modified by means of load amendment, and the influence of overlapping area on the pile - beam foundation is modified by means of stiffness amendment. by applying the model of stress - spread in shear - displacement method to describe the stress spread between piles and the geddes hypothesis to determine the stress distribution of pile, a displacement coefficient is deduced to calculate the flexibility matrix and the coefficient for load distribution of pile. considering the stiffness of foundation beam, the equation of the interaction of pile - beam - soil is established and an analysis program is developed related to the interaction
本文通過採用剪切位移法中的應力擴散模型考慮樁與樁之間的應力傳遞作用；採用geddes假定確定樁身和樁端的應力分佈，推導位移系數，並以此為基礎求得柔度矩陣；樁身和樁端的應力分佈大小由樁的荷載分配系數控制，通過迭代法可以求出樁的荷載分配系數；在考慮基礎梁對樁?梁?地基土共同作用的剛度貢獻基礎上，提出了樁?梁?地基土共同作用方程，並通過本文作者開發的相應計算程序，經實例計算驗證了本文方法的正確性。 -
The experimental results show that the seismic behavior of strengthened joints is improved significantly by the scheme, which successfully enhances the shear capacity by about 22 %, transforms the failure mode to be ductile, raises the ductility coefficient over 4, delays the strength degradation and stiffness degradation, and upgrades the energy dissipation capacity
試驗結果表明：加固能夠有效地提高節點的極限受剪承載力22 %左右，改變節點的破壞模式為梁端延性破壞，提高節點的延性系數到4以上，改善節點的承載力退化和剛度退化，提高節點的能量耗散能力，從而顯著改善了樑柱節點的抗震性能。
