Self-resetting swing glued wooden column with column boot

Abstract

The invention provides a self-resetting swing glued wooden column with a column boot. The self-resetting swing glued wooden column comprises the column boot, wherein the column boot comprises a bottomplate; a square steel tube is arranged on the bottom plate; stiffening ribs are arranged between the left side and the right side of the square steel tube and the bottom plate; the column boot is arranged between the bottom of the glued wooden column and a foundation; and the bottom of the glued wooden column is positioned in the square steel tube. A column foot of the glued wooden column is sleeved with the column boot, extra restoring force is provided for the glued wooden column to resist lateral load, and the anti-seismic property of the glued wooden column is improved. The outer column boot is placed on the top surface of the foundation in a floating manner, under the effect of horizontal force, the glued wooden column can be lifted along with the column boot to swing to dissipate energy, and self-resetting after an earthquake is realized by constraint moment of a disc spring on the column boot. The self-resetting swing glued wooden column is simple in structure and good in energy dissipation performance, and has high self-resetting ability.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a self-resetting swinging glulam column with a column shoe. Background technique [0002] At present, at the foot of the column of the wooden structure, most of them adopt the joint form of bolt connection. Common forms include steel filler plate, steel plywood and wood member 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. There are several problems with this node form: [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 horizontal grain of the wood, when the screw hole pin groove is under pressure, brittle failures such as splittin...

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 horizontal grain of the wood, when the screw hole pin groove is under pressure, brittle failures such as splitting of the horizontal grain of the column foot often occur, resulting in a decrease in the bearing capacity of the wooden column
