Provide Analytical Relationship to Calculate the Strength of Composite Steel Shear Walls by Abaqus software

Abstract

Composite steel plate shear wall is usually made up of a steel plate and also a reinforced concrete cover, which is attached to one side or both sides of the plate by means of a shearing device. In innovative composite steel plate shear wall system, a gap is created between concrete cover and boundary beams and columns. The presence of this gap in small earthquakes does not cause the concrete to interfere with the frame and thus prevent its failure. In relatively large quakes, this distance between the concrete wall and the boundary members is closed and added to the resistance of the system. In this paper, steel plate, concrete cover and frame were separated to calculate the strength of composite steel plate shear wall by their interaction. To evaluate the effect of concrete strength on composite steel plate shear wall strength, the gap between concrete cover and boundary members has been discussed, and then two relationships have been proposed to calculate the strength of composite steel plate shear wall. For this purpose, this paper has been used for analyzing pushover. In order to verify the numerical modeling, the characteristics of a steel plate shear wall model, composed of a laboratory study by Arabzadeh and colleagues at Tarbiat Modares University in 2011On the behavior of composite steel plate shear walls, it has been selected.
