Problems solved by technology

However, due to the anisotropy of wood and the low grain tensile strength and obvious brittle characteristics, the beam-column joints of wood structures are prone to brittle grain splitting failure, which makes the mechanical performance of wooden beams and wooden columns unavoidable. to take full advantage of

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a beam-column frictional energy-dissipating node for a glued wood structure. Background technique [0002] Green, ecological, environmental protection, low-carbon new materials and innovative structural systems are the inevitable direction of the development of civil engineering science and technology. Wood is one of the important varieties of energy-saving and environment-friendly biomass green materials. Especially under the current background of advocating energy saving and low carbon, the development of new wood structures has significant significance for reducing energy consumption of construction projects. [0003] Bolt connection is the most common connection form in wood structure joints. In wood structure beam-column bolt joints, it mainly uses the bending strength of bolts and the compressive strength of wood pin grooves to provide bearing capacity. However, ...
