Beam and column friction energy dissipation joint for laminated wood structure
The invention discloses a beam and column friction energy dissipation joint for a laminated wood structure. The beam and column friction energy dissipation joint comprises a connecting piece fixedly connected to the end of a wood beam or the side wall of a wood column, the connecting piece connects the wood beam with the wood column through a force bearing piece, and the wood beam is arranged perpendicular to the wood column. The connecting piece is connected with the wood column and the wood beam through common bolts correspondingly, and finally shape memory alloy is tensioned at reserved holes in the upper side and the lower side of the joint to form the laminated wood structure beam and column friction energy dissipation joint, the laminated wood structure beam and column friction energy dissipation joint has the advantages that through rotation of the joint, relative displacement between the beam end bolt and laminated wood is reduced, therefore, the cross grain tension effect of beam end wood is reduced, and the damage, caused by premature cross grain splitting of the beam end, to the overall structure is avoided; and meanwhile, the joint has good energy dissipation capacity and safety through the mode of early-stage rotating friction and later-stage bolt yielding.
一种胶合木结构用梁柱摩擦耗能节点，包括固结于木梁端部或者木柱侧壁的连接件，连接件通过承力件与将木梁木柱连接，所述的木梁与木柱垂直设置。连接件通过普通螺栓分别于木柱与木梁连接，最后在节点上下侧预留开孔处张拉形状记忆合金形成胶合木结构梁柱摩擦耗能节点，该节点的优点是通过节点的转动，减小梁端螺栓和胶合木间的相对位移，从而减小梁端木材的横纹受拉效应，避免因梁端过早出现横纹劈裂而使得整体结构破坏。同时，该节点通过前期转动摩擦，后期螺栓屈服的形式，使节点具有良好的耗能能力和安全性。
