Thin steel plate shear walls behavior and analysis

Steel plate shear walls have been used in buildings in North America and Japan. Until recently, the design practice has been to limit the strength of the wall to the buckling strength of the plate. The post-buckling strength of thin plates subjected to shear has been recognized for more than 60 years, since it was outlined by Wagner in the early 1930s. Tests of a quarter and one third scale specimens of thin steel plate shear walls under cyclic loading were performed; the tests are described and the results are summarized. An analytical model to determine the behavior of thin steel plate shear walls was developed and is given. The model is capable of depicting the behavior of walls with plates welded or bolted to the surrounding beams and columns of the building frame. Comparisons between the analytical and experimental results are made.

Experimental Study of Thin Steel‐Plate Shear Walls under Cyclic Load

The results of an investigation into the seismic behavior of unstiffened thin steel–plate shear walls is presented. Little work has been done in the past to investigate the behavior of unstiffened thin steel–plate shear walls in resisting lateral forces due to earthquakes or wind. Described is the cyclic testing of six, 1:4 scale specimens that include a moment-resisting frame, three specimens with varying plate thickness and moment-resisting beam-to-column connections, and two specimens with shear beam-to-column connections. Dissimilarities in behavior modes are found when the specimens of different plate thickness are compared to each other. The specimens with thinner plates exhibit an inelastic behavior that is controlled primarily by yielding of the thin plate, and the nonlinear system behavior is predominantly due to the stretching of the plate and the formation of a diagonal tension field. The specimens with thicker plates show an inelastic behavior that is primarily governed by the columns, and the capacity of the specimen with the thickest plate is limited by the instability of the column.

Nonlinear dynamic analysis of steel plate shear walls including shear and bending deformations

A nonlinear analysis of the dynamic response of thin steel plate shear walls, based on a finite difference solution of the governing differential equations of motion, is presented. The equations of motion incorporate both shear and overall bending displacements of the shear wall. The hysteretic characteristics of the individual storeys, incorporated in the nonlinear analysis, include the influence of shear buckling and plastic yielding of the web plate and plastic yielding of the surrounding frame. The results presented validate the analysis for elastic response and demonstrate the effectiveness of the hysteretic characteristics in inhibiting resonance.
