摘要:
试验研究了2组足尺重组木梁柱节点试件在单调荷载和往复荷载作用下的抗侧性能,探讨其破坏模式.试验结果表明,重组木节点具有较高的初始抗侧刚度和极限抗弯承载力以及较好的延性.与胶合木节点相比,使用相同长细比、个数和布置形式的螺栓实现同等的极限承载力时,重组木节点的峰值有效刚度和耗能能力分别提高约30%和90%.重组木材料强度、弹性模量和强重比的提高,有效强化了重组木梁、重组木柱与螺栓、钢填板间的相互作用,节点受力性能显著改善.
Abstract:
The lateral performances of two groups of full-scale beam-to-column specimens were investigated by the monotonic and reversed cyclic tests. The failure modes of the specimens were discussed. The results show that the scrimber connections have high initial lateral stiffness, ultimate moment resisting capacity and good ductility. To achieve the same ultimate moment resisting capacity with the same slenderness ratio, number and arrangement of bolts, the peak effective stiffness and the energy dissipation capacity of the scrimber connections are 30% and 90% higher than those of the glulam connections, respectively. The interaction among the scrimber beam, the scrimber column, the bolts and the steel plate can be effectively improved with the increase of the strength, the modulus of elasticity and the ratio of strength to weight of scrimber materials, thus improving the rotational behaviors of the connections.
