摘要:
本文对K型节点支管在轴力、平面内弯矩、平面外弯矩共同作用下的极限承载力进行试验研究,分析节点加载过程中应力发展过程及位移变化。结果表明:通过对支管施加偏心荷载能够有效地模拟节点承受轴力、平面内弯矩、平面外弯矩的共同作用,节点区主管的局部屈曲是K型相贯节点的破坏模式。采用Eurocode 3中K型节点的公式对支管承受轴力、平面内弯矩、平面外弯矩共同作用的K型节点进行验算是可行的,验算表明节点是安全的且偏保守。
Abstract:
The ultimate load capacity of the K-joint with the branch bearing axial force in-plane and out-plane bending moments was discussed.The stress developing process and the displacement of the joint were analyzed during the loading process.The axial force and the moment could be simulated by applying the eccentricity loading on the branch.The failure mode of the chord in the joint zone was local buckling.Using the Eurocode 3 specification formulas to check the axial force and bending moment of K-joints was feasible and conservative.
