Shear wall and connecting beam damping system with internally embedded energy consumption steel plate damping devices

Abstract

The invention discloses a shear wall and connecting beam damping system with internally embedded energy consumption steel plate damping devices and relates to an energy consumption device for a building structure. The shear wall and connecting beam damping system is characterized in that a main body part of the system consists of shear walls, a connecting beam and a high-ductility steel plate with a hole; the whole steel plate has an H shape or a horizontal straight line shape; the installation of the steel plate in construction engineering is carried out together with the binding of the shear walls and a connecting beam steel bar and the position of the steel plate is calibrated before concreting; and steel plate energy consumption dampers are arranged on the connecting beam and the shear walls at both ends of the connecting beam. The steel plate energy consumption dampers serving as non load bearing elements can increase the integral rigidity of the building structure. In case of an earthquake, the steel plate energy consumption dampers can effectively prevent the connecting beam from being damaged under the action of repeated load and make the energy consumption effect of the connecting beam more obvious so as to well protect the building structure.

Description

technical field [0001] The invention relates to an energy dissipation device for a building structure, in particular to a shear wall coupling beam damping system embedded with an energy dissipation steel plate damping device for vibration control of a building structure. Background technique [0002] Coupling beams generally have the characteristics of small span, large cross-section, and high stiffness of the wall connected to the coupling beam. Generally, under the action of wind load and earthquake load, the internal force of the coupling beam is often very large. Under the action of wind load and earthquake load, the wall pier produces bending deformation, which makes the coupling beam produce an angle, so that the coupling beam generates internal force. At the same time, the bending moment, shear force and axial force at the end of the connecting beam in turn reduce the internal force and deformation of the wall pier, play a certain role in restraining the wall pier, a...

However, under the repeated action of earthquakes, the cracks of the coupling beam will continue to develop and widen until the concrete is damaged under compression.
