Opening crossed-laminated-timber shear wall with energy-dissipation connecting piece

Abstract

An opening crossed-laminated-timber shear wall with an energy-dissipation connecting piece comprises a first crossed-laminated-timber shear wall (2) and a second crossed-laminated-timber shear wall (3). The first crossed-laminated-timber shear wall (2) and the second crossed-laminated-timber shear wall (3) are vertically spliced to form a vertical seam (6) above an opening. The crossed-laminated-timber shear wall (2) and the second crossed-laminated-timber shear wall (3) are assembled to a floor through first metal connecting pieces (4) and second metal connecting pieces (5). The opening crossed-laminated-timber shear wall is characterized in that the vertical seam is connected through the energy-dissipation metal piece (1). According to the opening crossed-laminated-timber shear wall withthe energy-dissipation connecting piece, the rigidity degeneration mode of the crossed-laminated-timber shear wall is improved to have a section of rigidity retention from full descent while the safety and reliability of the crossed-laminated-timber shear wall are guaranteed. After an energy dissipation device is destroyed, the crossed-laminated-timber with the energy dissipation device can continuously bear the load, and compared with a common crossed-laminated-timber shear wall, the ultimate displacement of the opening crossed-laminated-timber shear wall is increased by 45%, and the energydissipation capacity under the earthquake effect is improved.

Description

technical field [0001] The invention relates to a building structure technology, in particular to a wood structure technology, in particular to an open-mouthed orthogonal glued wood shear wall with energy-dissipating connectors. Background technique [0002] Wooden structures have a history of thousands of years in our country. With the development of science and technology in the construction industry, the technical barriers to the development of wooden structures have been broken, and wooden buildings have become more popular. The wood used in wooden buildings has a high strength-to-weight ratio, and the materials are renewable and environmentally friendly. The assembly rate of wooden structure buildings is high, and the development of wooden buildings meets the assembly and sustainable development requirements of the construction industry. In foreign countries, with the development of medium and high-rise timber structures, cross-laminated-timber (cross-laminated-timber)...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to design an energy-dissipating connector in the connecting beam for the problem that the conventional connection of the connecting beam above the opening in the opening CLT shear wall is damaged and the rigidity and bearing capacity of the system drop sharply. For the connected openings of the orthogonal glulam shear walls, by setting energy-dissipating connectors in the middle of the connecting beams, the deformation is first concentrated in the energy-dissipating parts, which improves the energy-dissipating capacity of the system; for a plateau
