Seismic behaviour of stiffened steel plate shear walls

Abstract

The need of seismic upgradation in building structures has gained importance in recent years. For lateral load resistance system steel plate shear wall had more advantages compared conventional lateral load resisting systems used for earthquake resistant design of structures due to robust post-buckling strength, substantial ductility, stable hysteretic characteristics and high initial stiffness. In the present paper various aspect of Steel plate shear wall (SPSW) is studied are discussed and opinions of various researchers have been considered with different approaches. Discussion of analytical, experimental and Finite elementmethods using different material composition, connectivity consideration and codal provision aspect are also discussed which may help for advance analysis and design methodologies for the engineering community. The existing design guidelines for the SPSW system in current US and Canadian codes are also discussed.The new concept of low yield point (LYP) steel having improved serviceability, structural performance, and enhanced energy absorption characteristics in design of SPSW is also studied.
