Abstract
Steel shear panels in combination with bracing are a novel form of steel shear walls that eliminate large distributed loads to impose on primary beams along with columns. This paper presents the results of a comparative experimental program on two types of steel shear panels with and without stiffeners. For this purpose, the proposed quasi-static cyclic loading history of Federal Emergency Management Agency(FEMA) 461 was applied on two full-scale specimens. Structural steel was selected as the material of the panels, which were welded to the surrounding boundary elements. In addition, using finite element models, performed tests were simulated and scaling effects were investigated. This study identified that steel shear panels have acceptable hysteretic behavior in addition to excellent ductility, which cause more dissipation of induced seismic energy. Comparison of seismic performance of two types of steel shear panels and high cost of setting up stiffeners demonstrate that unstiffened shear panel is a reliable selection for seismic-resisting systems. The results of numerical study show that acceleration-based similitude laws have acceptable estimation for responses of scaled models. Copyright © 2015 John Wiley & Sons, Ltd.
