Thickness changeable shear wall with oblique reinforcing bar transition layer and construction method thereof

Abstract

The invention relates to a building method for a thickness variable shear wall with an oblique reinforcing bar transition layer and the shear wall designed by the method. The shear wall consists of common thickness variable wallboards and steel bar oblique supports, wherein reinforcement mats consisting of transverse steel bars and longitudinal steel bars are arranged in the common thickness variable wallboards, and the reinforcement mats are jointed by pull-joint steel bars; the wall thickness variable areas of the thickness variable wallboards are provided with the steel bar oblique supports which are bound with the reinforcement mats and bound with the pull-joint steel bars; and the steel bar oblique supports are X-shaped, and the upper ends and the lower ends of the steel bar oblique supports extend the upper shear walls and the lower shear walls of the common thickness variable wallboards respectively. Compared with the prior shear wall, the shear wall has the advantages of largeinitial rigidity at variable sections, high carrying capacity, slow attenuation of bearing capacity and rigidity, more aseismatic defensive lines, good integral performance of aseismatic energy consumption, and relative stability of post aseismatic performance.

Description

Variable-thickness shear wall with diagonal reinforcement transition layer and construction method thereof Technical field The invention relates to a variable thickness shear wall with an oblique reinforcement transition layer, which belongs to the field of shear wall structures. Background technique In today's building structure, the shear wall is the core seismic component of the building structure, which bears 80% of the earthquake effect of the whole structure. However, the poor ductility of the shear wall affects the full use of the overall seismic performance of the structure. Especially at the variable cross-section of the shear wall, sudden changes in shear stiffness are prone to occur, and weak parts affect the seismic performance of the entire structure. Therefore, improving the ductility and comprehensive seismic performance of the transition layer shear wall with variable section thickness has become a key technical issue for the variable section shear wall. The e...

Problems solved by technology

The existing problem is that a sudden change in stiffness is formed at the place where the wall thickness changes suddenly, so that there is a weak link in the shear performance of the overall shear wall

The problem is that there is a weak link in the transition zone, and the construction of the inwardly bent part of the steel bar is difficult, and it is difficult to ensure the construction quality
