Energy dissipation shear wall with built-in trusses and construction method of shear wall

Abstract

The invention discloses an energy dissipation shear wall with built-in trusses and a construction method of the shear wall. The energy dissipation shear wall comprises shear wallboards, the trusses are arranged between the shear wallboards, an edge frame is arranged on the peripheries of the shear wallboards, the trusses are fixedly connected with the edge frame, the edge frame comprises an upper edge frame beam, a lower edge frame beam, a left edge frame column and a right edge frame column, grouting sleeves are pre-buried on the left side of the upper edge frame beam and the left side of the left edge frame column, the right edge frame column is provided with transverse steel ribs extending out of the right edge frame column, and vertical steel ribs are extending out of the lower edge frame beam are arranged on the lower edge frame beam. The trusses are arranged in the steel rib concrete shear wallboards to have a certain reinforcing function on the shear wallboards, anti-seismic lateral rigidity is larger than that of a conventional steel rib concrete shear wall, and good energy-dissipation and anti-seismic functions are achieved. The built-in trusses divide the shear wallboards into a plurality of small wall columns, during large earthquakes, energy is dissipated through local yielding, stability outside the whole plane is enhanced, and the shear wallboards are moved through the trusses to achieve the anti-seismic function as a whole.

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.
