Abstract

           Composite Steel Plate Shear Walls (CSPSW) are a developed type of steel shear walls that can be used in two ways to form the buckling due to the buckling in the steel sheet in these walls. One method is to use metal hardeners and the other is to use a concrete cover that is attached to the steel sheet through cutters. The second type is known as composite shear wall. In steel shear wall, the floor shear is transferred using the tensile field of the steel plate and after buckling due to diagonal pressure. In a composite cutting wall, the concrete wall preserves the steel plate and prevents it from buckling before yielding to pressure. As a result, the steel plate resists the sheer force of the floor due to shear yield. The shear yield capacity of a metal plate is clearly greater than the capacity it seeks to obtain with the help of a diagonal tensile field. In addition, the compacted concrete wall provides insulation against sound and temperature, and makes steel shear walls resistant and fire-retardant for steel sheets. However, due to architectural and installation reasons, these walls need to be opened. So with modeling as well as recommendations and criteria related to composite shear walls from different regulations to make a relationship for the case that we want to design the wall with opening with the given relations without opening, we have finally done the process of seismic design in composite shear wall systems, along with some design recommendations, it is stated about the design of composite shear wall components.
