Abstract Share this page

Steel plate shear walls have been used for building design in both North America and Japan, but with different design and detailing strategy. One approach employs heavily stiffened steel plate shear walls to ensure that the wall panel achieves its full plastic strength prior to out-of-plane buckling, An alternative approach is to use slender unstiffened steel wall plates, which exhibit nonlinear behavior at relatively small story drifts as they buckle out of plane. In this paper, a nonlinear finite element model of a one single- and a four-story thin (unstiffened) steel plate shear walls were developed, then by using saved energy in plate and frame of the thin steel plate shear walls, portion of frame and plate from total stiffness of the steel plate shear walls were separated and with varing the columns flexural stiffness, variations of stiffness of the thin steel plate shear wall, frame and plate; effect of interaction between frame and plate on frame and plate stiffness; and also variations reactions in the plate length edge connection to foundation are considered. Results are indicated that increasing of inertia moment of the columns is effected considerably on behaviuor the thin steel plate shear wall.
