Multilayer oblique slotted self anti-buckling steel plate shear wall and manufacturing method thereof

Abstract

The invention discloses a multilayer oblique slotted self anti-buckling steel plate shear wall comprising multilayer oblique slotted steel plate shear walls; slot holes of the oblique slots can divide the steel plate shear wall into a plurality of oblique plate strips; the slotting direction of the oblique slots of the same layer steel plate shear wall is same; the oblique slot directions of two adjacent layers of steel plate shear walls are opposite to each other; the two adjacent layers of the steel plate shear walls are bonded through a damping rubber; the surrounding of the multilayer steel plate shear walls is connected with an edge frame; under reciprocating horizontal earthquake load effect, the oblique plate strips of same direction are respectively under unidirectional pulled or unidirectional pressed states; the tension force rigidity of the pulled oblique plate strips in certain layer can provide external-plane support for the pressed oblique plate strips of another layer, thus realizing self anti-buckling effect. The multilayer oblique slotted self anti-buckling steel plate shear wall can serve as a novel bearing dissipating energy type anti-side force member, can effectively reduce lateral deformation of multi-storey high-rise building under horizontal load, thus enhancing dissipating energy capability of the multi-storey high-rise building under earthquake loads.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a multilayer obliquely grooved damping rubber bonded self-buckling-resistant steel plate shear wall and a manufacturing method thereof. Background technique [0002] Steel plate shear walls have good ductility, large lateral stiffness and energy dissipation capacity, and are widely used in high-rise and super high-rise buildings in high-intensity areas at home and abroad. Early steel plate shear walls used elastic buckling load as the limit state of bearing capacity, resulting in very thick steel plates or very dense stiffeners. On the one hand, it resulted in waste of materials, and on the other hand, the energy dissipation capacity of steel after plastic yielding could not be utilized. However, reducing the thickness of the steel plate to utilize its energy dissipation capacity after plastic yielding also reduces the buckling capacity of the steel plate under obl...

Problems solved by technology

[0006] There are also steel plate shear walls with oblique grooves, the strips between the grooves are only subjected to tension and pressure, and the steel plates mainly subject to shear deformation are transformed into columns mainly subject to tension and compression, which improves the deformation capacity and However, the steel plate shear wall with inclined grooves set up in a single layer has good energy dissipation capacity under the tension of the steel plate in the groove only under the horizontal shear force in one direction; but it will be compressed under the horizontal load in the opposite direction. , so that buckling occurs, it is necessary to install concrete cover plates or stiffeners to prevent buckling on both sides of the steel plate
