In recent years steel plate shear walls are widely used in tall building construction especially in Japan and United states. Excellent seismic performance and saving the construction cost are the important reasons of using these systems. Two types of steel plate shear walls that conveniently used are stiffened and unstiffened types. Stiffened types are very costly and unstiffened types have some serviceability problems after earthquake event.
An innovated type of steel shear wall which made up of corrugated steel plates is introduced. The structural Behaviour of corrugated steel shear wall systems with its boundary columns and beams in each story is more or less similar to steel plate girders with corrugated webs and might remove most of stiffened and unstiffened steel shear wall` deficiencies. Reduced wall stiffness due to accordion effect, achieving a stiffened steel plate shear wall with relatively thin plates and mobilizing the inherent geometric stiffness of plate, ease of erection, good seismic performance and energy dissipation and visual esthetics in expose construction are main advantages of these structural systems.
The behavior is investigated by FEM method. Theses analyses are geometrically and materially nonlinear and the relation between corrugated plate dimensions and its seismic performance are discussed.
