An energy-dissipating shear wall with built-in trusses and its construction method

Abstract

The invention discloses a built-in truss energy-dissipating shear wall and a construction method thereof, comprising shear wall panels, trusses are arranged between the shear wall panels, and edge frames are arranged around the shear wall panels. The truss is fixedly connected to the edge frame, and the edge frame includes an upper edge frame beam, a lower edge frame beam, a left edge frame column, and a right edge frame column. The upper part of the upper edge frame beam and the left edge of the left edge frame column are pre-buried and grouted A sleeve, the right edge frame column is provided with transverse reinforcement bars extending out of it, and the lower edge frame beam is provided with vertical reinforcement bars extending out of it. The truss of the invention is embedded in the reinforced concrete shear wall panel, and has a certain stiffening effect on the shear wall panel. The built-in truss divides the shear wall panel into a number of small wall members. During a major earthquake, energy is consumed by local yielding, which enhances the overall out-of-plane stability. The truss mobilizes the shear wall panel to play an overall anti-seismic role.

Description

technical field [0001] The invention relates to a built-in truss energy-dissipating shear wall and a construction method thereof. Background technique [0002] Entering the 21st century, the industrialization of construction is an inevitable trend of the development of the construction industry, and residential buildings are gradually developing towards the high-rise building structure of the industrialization model. High-rise buildings put forward higher requirements on the seismic lateral stiffness of the structure. Conventional reinforced concrete shear walls need to arrange a large number of steel bars to resist the earthquake shear force, but the effect of increasing the ductility and bearing capacity of the shear wall is very weak after the reinforcement ratio reaches a certain level. Because the mechanical connection cannot be formed between the blocks, the prefabricated block shear wall cannot meet the requirements of the lateral stiffness of high-rise buildings. T...

Problems solved by technology

Conventional reinforced concrete shear walls need to arrange a large number of steel bars to resist the earthquake shear force, but the effect of improving the ductility and bearing capacity of the shear wall is already very weak after the reinforcement ratio reaches a certain level

Because the mechanical connection cannot be formed between the blocks, the prefabricated block shear wall cannot meet the requirements of the lateral stiffness of high-rise buildings.
