摘要:
本文对一种安装预应力钢绞线的新型重型胶合木梁柱节点的抗侧力性能进行了研究,该节点通过对钢绞线施加预应力产生自复位能力,并设计一种特制“钢帽”作为耗能件,安装于梁端。为探究该试件性能,采用单调加载和低周往复加载的方式,得到试件的承载力、耗能性能、破坏模式和抗侧性能等。结果表明:节点具有良好的变形能力,加载过程中,特制“钢帽”作为主要耗能件,提供较好的耗能能力,钢绞线在加载全程均处于弹性状态。该设计达到设计目标,试件耗能及自复位性能良好。
Abstract:
The lateral performance of a pre-stressed energy dissipating beam-to-column joint for glulam heavy timber structure was investigated in this paper.Such connection incorporates post-tensioned high-strength strand to provide self-centering capacity.The energy is dissipated by a special steel cap,which is attached with the timber beam and also to prevent the end bearing failure of wood.A series of monotonic tests as well as cyclic loading tests were conducted.The tests were conducted with two different post-tension forces in the steel strands. The results prove the good moment-resisting and energy dissipation capacity of joints.The steel strand remains elastic during the entire tests and its nonlinear inelastic behavior is blamed for the deformation of wood and geometrical nonlinearity of joints.
