Anti-buckling oblique notching steel plate energy dissipation shear wall

Abstract

The invention relates to an anti-buckling oblique notching steel plate energy dissipation shear wall which belongs to the technical field of structural engineering. The anti-buckling oblique notching steel plate energy dissipation shear wall consists of an oblique notching steel plate, concrete slabs and an edge frame, wherein the concrete slabs are arranged at both sides of the steel plate and are used for restraining out-of-plane deformation of the steel plate; the edge frame is connected with the steel plate; the steel plate is provided with different forms of chutes designed as required; the periphery of the steel plate is connected and embedded into the edge frame by bolts; the bolts passing through the chutes are connected with the concrete slabs at both the sides. By forming the different forms of chutes on the steel plate, a complex stress state of the steel plate is changed, and a stress mode of taking tension and compression deformation of the steel plate among the chutes as the major mode is formed, and thus, not only is the anti-buckling oblique notching steel plate energy dissipation shear wall beneficial for implementing stable tension and compression energy dissipation, but also parameters of inclined plates among the chutes can be regulated by changing the forms and the sizes (length and width) of the formed chutes, and an inefficacy mechanism of the shear wall is effectively controlled, so that resist lateral stiffness, intensity and ductility of the shear wall can be regulated. Used as a novel lateral force resisting and energy dissipation component, the anti-buckling oblique notching steel plate energy dissipation shear wall can be widely applied to multilayer and high-rise structures.

Description

technical field [0001] The invention relates to a novel energy-consuming and anti-buckling steel plate shear wall with inclined grooves, which belongs to the technical field of structural engineering. Background technique [0002] In the seismic design, how to reduce the irreversible damage (such as plastic deformation) of the building structure (including the main stress components and non-structural components) during the earthquake, so that the structure can be repaired quickly after the earthquake and can be used normally is the current engineering Hotspots of earthquake resistance research. The introduction of energy-dissipating components is a very effective method. Setting energy-dissipating components in the structure can effectively dissipate the input energy of the earthquake, so that the deformation of the structure is mainly concentrated in the energy-dissipating components and avoid damage to other components in the structure.

Problems solved by technology

However, the steel plate in the shear wall is in a complex stress state, and it is difficult to control the failure mode of the shear wall, so it is impossible to accurately judge its yield load and yield displacement, and it is not easy to realize the controllable design of parameters (yield displacement, yield force); At the same time, in current engineering applications, the steel plate is mostly a whole steel plate. When the size of the edge frame and the yield strength of the steel are constant, the strength and stiffness of the steel plate are only related to the thickness of the steel plate. When the steel plate shear wall is applied to multi-story buildings, the thickness of the steel plate is often increased because the design thickness is too thin to meet the processing requirements, resulting in waste of steel, which greatly limits The popularization and application of steel plate shear wall in multi-high-rise buildings
