摘　　要：为研究不同松动对大头榫节点抗震性能的影响,按云南"一口印"传统穿斗式木构架做法,选用杉木由作了3个大头榫节点模型,大头榫节点松动采用削减榫头宽度的方法来模拟。通过低周期的往复载荷试验,研究了3个大头榫卯节点的损伤形态,弯矩转角滞回曲线,骨架曲线,刚度退化规律和能量耗散能力。In order to study the effect of different loosening on the seismic performance of the bulkhead joints, according to the practice of "one seal" traditional wear bucket wooden frame, the Chinese fir was made up of three big head and tenon joint model, and the big tenon joints were used to reduce the tenon width simulation. The damage morphology, bending moment hysteresis curve, skeleton curve, stiffness degradation law and energy dissipation capacity of three bulkhead joints were studied by low cycle reciprocating load test.
