Self-resetting swing laminated wood frame with column boots

Abstract

The invention provides a self-resetting swing laminated wood frame with column boots. The self-resetting swing laminated wood frame comprises symmetrically-arranged laminated wood columns, wherein laminated wood beams are arranged on the upper sides between the laminated wood columns; the column boots connected with a foundation are arranged at the bottoms of the laminated wood columns; and the laminated wood columns and the laminated wood beams are connected through steel hinge joints. According to the self-resetting swing laminated wood frame, by relaxing the constraint between the laminatedwood columns and the foundation and between the beams and the columns, the structure swings under the earthquake action to dissipate earthquake energy, under the action of the constraint torque formed by the initial pre-pressure of belleville springs on the column boots, post-earthquake self-resetting of the laminated wood frame is achieved, and residual deformation of the structure is reduced. The self-resetting swing laminated wood frame is easy and convenient to construct and high in energy dissipation capacity and self-resetting performance.

Description

technical field [0001] The invention relates to the technical field of anti-seismic structures, in particular to a self-resetting swing glued wood frame with column shoes. Background technique [0002] The glulam structure has the characteristics of resource regeneration, energy saving and environmental protection, light weight and beautiful appearance, and has a high degree of assembly and good seismic performance. However, most traditional glulam structures adopt the joint form of steel filler bolt connection. This joint form mainly uses the bending resistance of the bolt and the local pressure of the wood at the bolt to provide bearing capacity. This node form mainly has the following problems: [0003] 1. Due to construction deviation, there is a gap between the bolt hole wall and the bolt on the wooden column. This gap causes the wooden beam to slide after being stressed, resulting in a low initial stiffness of the joint. [0004] 2. Due to the low tensile strength of...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to construction deviation, there is a gap between the bolt hole wall and the bolt on the wooden column. This gap causes the wooden beam to slide after being stressed, resulting in a low initial stiffness of the joint

[0004] 2. Due to the low tensile strength of the transverse grain of the wood, when the screw hole pin groove is under pressure, brittle failures such as splitting of the transverse grain of the glued wood often occur, resulting in a decrease in the bearing capacity of the glued wood structure
