Ductility of Thin Steel Plate Shear Walls

The idea of using steel plate shear wall as a lateral load resisting system in design andretrofit of structures has attracted the attention of researchers and designers for more than three decades. In this research, the ductility of thin steel plate shear walls are studied based on ATC-24 protocol and Popov’s definition. Two three-story unstiffened steel plate shear walls were tested under cyclic loading. In these tests shear walls had rigid and simple beamto- column connections. For the plate of panels, low strength steel and for the boundary frame high strength steel were used. In addition, some other valid tests on steel plate shear walls with different configurations, which were done in the world also, were considered. The results obtained from all of the tests show that the ductility factor in thin steel plate shear walls according to ATC-24 protocol and Popov''s definitions can be assumed about 6.5 and 13, respectively.
