Abstract

The invention relates to a sectional steel plate shear wall which has no cementation and can prevent the flection and belongs to the technical field of the constructional engineering. The invention is characterized in that: the shear wall consists of an internally-embedded steel plate unit, an external limiting unit and a boundary member; the external limiting unit consists of a plurality of sectional concrete covers and reinforcing ribs made of formed steel; the boundary member consists of an edge pillar and an edge beam; A vertical reinforcing rib made of formed steel and a transverse reinforcing rib made of formed steel are arranged between the sections. The internally-embedded steel plate and the concrete covers in each section are connected by a bolt which can penetrate The internally-embedded steel plate and the concrete covers or a prestressed bolt; the internally-embedded steel plate and the vertical reinforcing rib made of formed steel as well as the transverse reinforcing rib made of formed steel are connected by the bolt or the prestressed bolt. The steel plate shear wall provided by the invention is a novel member to resist the side force for the steel structure or other structure of the high-rise building, and is characterized by good earthquake-resistant performance, high ductility, plumb energy-saving hysteresis loop, easy construction and so on and is an excellent shock-resistant and energy-consuming member.

Description

technical field [0001] The invention relates to a novel lateral force-resistant, block-type unbonded buckling-resistant steel plate shear wall, which belongs to the technical field of structural engineering. Background technique [0002] In the early stage of the development of steel plate shear walls, the elastic buckling load was used as the limit state of the bearing capacity of the steel plate wall, so the steel plate wall designed in the early stage was generally very thick or the stiffeners were very dense. Although this kind of thick steel plate shear wall or stiffened steel plate wall has good energy dissipation capacity, high rigidity and shear bearing capacity, its biggest disadvantage is waste of materials and high cost, and at the same time, the excessive rigidity makes the steel frame ahead of The damage of the steel plate wall is not allowed by the principle of seismic fortification; considering the economy, the thin steel plate wall is the first choice for des...
