Problems solved by technology

However, most of the current research focuses on the single-piece self-resetting shear wall and the traditional shear wall with replaceable coupling beams. Although the single-piece self-resetting shear wall can reduce the seismic damage of the wall, it cannot reduce the traditional shear wall connected to it. The failure of the coupling beam, although the traditional shear wall with replaceable coupling beam can reduce the damage of the non-yielding section of the coupling beam, the protection effect on the wall is limited

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] As shown in the drawings, the present invention is a self-resetting shear wall with a replaceable connecting beam, which is composed of a replaceable connecting beam and a self-resetting shear wall connected thereto, and the replaceable connecting beam is composed of a replaceable connecting beam The replacement section 2 and the non-yielding section 3 are composed, and the self-resetting shear wall is a post-tensioned unbonded prefabricated shear wall 1 .

[0022] The replaceable section 2 is a metal energy-dissipating component or a viscoelastic damping energy-dissipating component or a frictional damping energy-dissipating component or a composite damping energy-dissipating component.

[0023] The non-yielding section 3 is a steel component or a steel-concrete composite component or a reinforced concrete component.

[0024] The prestress of the pos...

Abstract

The invention relates to self-reset shear walls with replaceable coupling beams and belongs to the field of aseismic structure systems. The self-reset shear walls are composed of replaceable coupling beams and self-reset shear wall bodies connected with the replaceable coupling beams. The replaceable coupling beams are composed of replaceable sections and non-yielding sections, and the self-reset shear wall bodies are post-tensioned un-bonded pre-cast shear walls. According to the self-reset shear walls, the concept is clear, construction is convenient, the safety of main body structures can be effectively protected during middle earthquakes or major earthquake, repair and replacing of damaged members after earthquakes are facilitated, and the self-reset shear walls are applicable to important building structures in high-intensity earthquake regions.

Description

technical field [0001] The invention relates to the field of anti-seismic structural systems, in particular to a self-resetting shear wall with replaceable connecting beams. Background technique [0002] The self-resetting shear wall is a new type of structure, which can reduce the damage of the wall through the uplift of the bottom of the wall during a moderate earthquake or a large earthquake, and the replaceable connecting beam is a replaceable energy-consuming part installed on the connecting beam , during an earthquake, the energy consumption of the replaceable energy-dissipating parts can be used to reduce the damage of the rest of the coupling beam and the wall, and it is convenient to repair and replace the replaceable energy-dissipating parts after the earthquake. However, most of the current research focuses on the single-piece self-resetting shear wall and the traditional shear wall with replaceable coupling beams. Although the single-piece self-resetting shear wa...
