Concrete self-parting composite shear wall with built-in UHPC (Ultra High Performance Concrete)

Abstract

The invention relates to a concrete self-parting composite shear wall with built-in UHPC (Ultra High Performance Concrete), and belongs to the technical field of building structures. Comprising a concrete wall body, a reinforcement cage and a plurality of steel pipes are embedded in the concrete wall body, the steel pipes are arranged on the inner side of the reinforcement cage, the steel pipes are vertically arranged, the steel pipes are arranged at intervals in the length direction of the concrete wall body, and the steel pipes are filled with high-strength concrete. The problems that a concrete shear wall in the prior art is poor in anti-seismic property and the like are solved.

Description

technical field [0001] The invention relates to a concrete self-partitioning combined shear wall with built-in UHPC, which belongs to the technical field of building structures. Background technique [0002] Shear wall, also known as wind-resistant wall, earthquake-resistant wall or structural wall, is a wall in a house or structure that mainly bears horizontal load and vertical load (gravity) caused by wind load or earthquake, and can prevent structural shear. Cut (shear) damage, also known as seismic walls, generally made of reinforced concrete. [0003] The currently commonly used shear walls are reinforced concrete shear walls. This type of shear wall is prone to brittle shear failure under high-intensity earthquakes, leading to building collapse, and there is room for improvement in bearing capacity and ductility. [0004] The prior art application number is: 202110696789.9 patent document discloses a modular assembly type shear wall, including a first wall, a second w...

Problems solved by technology

[0006] In order to overcome the shortcomings of existing concrete shear walls such as poor seismic performance, the present invention designs a concrete self-slit combined shear wall with built-in UHPC. The present invention introduces steel pipes with built-in UHPC into the shear wall structure, greatly improving The load-carrying capacity and ductility of the shear wall are improved, and vertical cracks will be generated at the position where the steel pipe is placed during a high-intensity earthquake, making the whole wall into a split wall, changing the failure form of the wall from the brittle shear wall of the ordinary shear wall The shear failure is transformed into ductile failure, showing the characteristics of self-adaptive splitting, giving full play to the performance of each material, and has a good application prospect
