Shear wall with inbuilt continuous-row steel tube concrete core column and soft steel energy consumption bond and manufacturing method thereof

Abstract

The invention discloses a shear wall with an inbuilt continuous-row steel tube concrete core column and a soft steel energy consumption bond and a manufacturing method thereof, belonging to the field of steel tube concrete combined shear wall. The shear wall comprises a combined steel tube concrete frame and a shear wall body, wherein the shear wall body comprises a steel tube concrete core column and a soft steel energy consumption bond, and the left end and the right end of the steel plate energy consumption bond are fixedly connected with the core column and the steel tube concrete frame; two sides of the continuous-row core column are provided with longitudinal and transverse mat reinforcements, and reinforcements on two sides are connected by binding rebars; soft steel energy consumption short steel plates the strength of which is smaller than that of the steel plate are arranged between the core columns and between the core column and a frame column, thus greatly improving the ductility and the flexural rigidity of the shear wall; meanwhile, because the short steel plate is equivalent to a connecting beam, the effect of invisible 'strong column and week beam' can be realized; and the soft steel energy consumption bond, the concrete wall body, the frame column and the core column jointly form three defensive lines of a lateral force resisting system. The invention adopts the steel tube concrete core column and the soft steel energy consumption bond as the lateral force resisting system, improves the vertical rigidity and the bearing capacity of the shear wall, has the advantages of convenient construction and shortened construction period and is more economical.

Description

technical field [0001] The invention is a shear wall with built-in continuous rows of steel pipe concrete core columns with soft steel energy-dissipating keys [0002] The invention and a manufacturing method thereof belong to a shear wall and a manufacturing method thereof. Background technique [0003] In recent years, with the development of social production and the needs of people's lives, there are more and more large and complex high-rise buildings pursuing individualization, and the requirements for the seismic performance of the overall structure are also getting higher and higher. Reinforced concrete high-rise buildings with large quantities and wide areas are usually composed of beams, columns, floors, shear walls and cylinders. Shear walls and cylinders composed of shear walls are the core parts of high-rise building anti-seismic, so the shear wall structure The seismic performance of high-rise buildings plays a vital role in the safety and reliability of high-r...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to significantly improve the bearing capacity, ductility, and seismic energy consumption capacity of composite shear walls, and combine the advantages of composite steel pipe concrete, steel pipe concrete and soft steel plates in energy consumption. Outsourcing concrete on both sides of the concrete core column solves the problem of out-of-plane instability of the core column. A series of built-in steel tube concrete core columns with soft steel energy-dissipating key composite shear walls are designed. The composite steel tube concrete frame columns can be built-in steel frames. It can also be a combination of built-in steel pipe core columns. The present invention only takes the built-in steel column combined with steel pipe concrete frame column as a special case. The outer steel pipe is square in consideration of the construction cost, and the shape of the row of core columns in the wall can be square or round. etc., the quantity depends on the actual situation
