The steel shear wall has been introduced as a system with high stiffness and strength and a considerable capability to absorb seismic energy. Due to its special advantages compared to other lateral load-resistant systems, this system is being used in tall buildings more and more frequently. Using corrugated sheets together with flat sheets increases the sheet's elastic resistance and the ductility of the lateral bearing system. Therefore, in this article, it is suggested that a combination of corrugated and flat sheets be used for the steel wall. This research investigates the stiffness of a shear wall consisting of corrugated and flat plates. The shear wall plates consist of two trapezoidal corrugated plates and two flat plates connected with high-strength bolts. This proposed shear wall can be replaced in tall buildings as an alternative to the normal corrugated plate shear wall to resist lateral shear loads caused by seismic or wind effects. In this research, stiffness constants, including bending stiffness constants in orthotropic directions and torsional stiffness constants, have been theoretically derived using elastic theory. Then, by comparing the relationships of stiffness constants and using its results for the frame-wall interaction theory, the accuracy of these extracted relationships for use in modeling purposes and estimating seismic parameters without the need for finite element modeling is confirmed with sufficient accuracy
