Problems solved by technology

Steel plate shear walls are mainly used as lateral force-resistant components in steel structure buildings. However, ordinary steel plate shear walls have weak blast resistance, and their resistance is significantly reduced under the action of explosive loads. damage, and even cause partial collapse of steel structures

Abstract

The invention relates to the technical field of construction, in particular to a dual-layer corrugated steel plate-polyvinyl alcohol-engineered cementitious composite combined anti-knock shear wall. The technical scheme includes that the anti-knock shear wall comprises dual-layer corrugated steel plates, PVA-ECC (polyvinyl alcohol-engineered cementitious composite) plates, foamed aluminum, a pair of H-shaped steel frame posts and a pair of H-shaped steel frame beams, wherein the dual-layer corrugated steel plates wrap the PVA-ECC plates, the positions between the corrugated steel plates and the PVA-ECC plates are filled with the foamed aluminum, the H-shaped steel frame posts and the H-shaped steel frame beams are connected mutually to form a shear wall frame, and the corrugated steel plates are fixedly connected with the shear wall frame. The dual-layer corrugated steel plate-polyvinyl alcohol-engineered cementitious composite combined anti-knock shear wall has the advantages that anti-knock performance of the corrugated steel plate shear wall can be improved, loss of lateral resistance of the corrugated steel plates due to bending of the corrugated steel plate shear wall is reduced, and local structural damage, casualties and property losses are avoided.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an explosion-resistant shear wall composed of double-layer corrugated steel plates, polyvinyl alcohol cement-based composite materials. Background technique [0002] At present, steel structures are often used in high-rise, super-high-rise office buildings, new steel structure residences and commercial centers. Steel plate shear walls are mainly used as lateral force-resistant components in steel structure buildings. However, ordinary steel plate shear walls have weak blast resistance, and their resistance is significantly reduced under the action of explosive loads. damage, and even cause partial collapse of steel structure buildings. Contents of the invention [0003] The invention provides a double-layer corrugated steel plate polyvinyl alcohol cement-based composite material combination anti-explosion shear wall, which can improve the anti-explosion performance of the...
