Problems solved by technology

[0005] The purpose of the present invention is to propose a swingable and self-resetting prestressed cross-glued wood joint for the technical defects of insufficient energy dissipation capacity, large residual deformation and poor repairability of existing cross-glued wood shear walls. The shear wall, through the prestressing technology and the design of ductile connectors, realizes the swing energy dissipation and self-resetting of the cross-glued wood shear wall, and the structure of the double-leg shear wall meets the needs of openings in the external wall

Abstract

The invention relates to a prestress orthogonal laminated wood coupled shear wall capable of achieving swinging and self-resetting. The shear wall is characterized by comprising an orthogonal laminated wood coupled wall column (1), orthogonal laminated wood connecting beams (2), a reinforced concrete foundation (3), prestress reinforcing steel bars (4) and connectors (5). The shear wall has the advantages that earthquake resistance is achieved through the swinging and self-resetting of the wall column and the rotation of the connecting beam ends, earthquake energy can be dissipated, residual deformation after an earthquake is small, and component replacement after the earthquake is facilitated by controlling an energy dissipation mechanism and a failure mode; meanwhile, the structure of the coupled shear wall satisfies the external wall hole opening requirements, and the shear wall is simple in structure, convenient in construction and convenient to popularize.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a swingable and self-resetting prestressed cross-glued wood coupled shear wall, which is used for multi-storey wooden buildings with higher requirements on seismic performance. Background technique [0002] At present, my country is vigorously promoting the development of modern multi-layer wood structures, and the application of glued wood structures is the most common. Orthogonal glulam is a prefabricated engineered wood panel composed of at least 3 layers of solid wood sawn timber or structural composite panels orthogonally assembled with structural adhesives. It has stable dimensions, light weight and high strength, excellent bidirectional mechanical properties, and green With the characteristics of environmental protection and high degree of industrialization, it has great development potential as a load-bearing material for multi-layer wood structures....
