Analytical and Numerical Study on Bending and Shear Effects of Steel Plate Shear Walls

Steel Plate Shear Walls in recent decades as a lateral load resisting system of buildings, especially tall buildings have been discussed. Using this system in tall buildings requires a detailed analysis on behavior of Steel Plate Shear Walls. In tall buildings, bending deformations are more effective. So in this research, three-story Steel Plate Shear Walls are analyzed by modified - slop deflection method which considers bending deformations. The plates in this system are equaled by diagonal springs. Plate - frame interaction method is used for calculating plate stiffness. The process of analysis is conducted in a programming language in order to reduce analysis time. Analytical results in compare with finite element analysis show incorrect assumption in plate - frame interaction method for making complete diagonal tension field in post-buckling phase should be modified. After modifying, analytical results in compare with finite element analysis show good coincidence.
