seismic upgrading of non-ductile steel frames using steel plate shear walls
many old damaged and undamaged building structures do not meet the criteria of modern seismic design codes. such structures need to be seismically enhanced. the main objective of this paper is to propose and validate the effectiveness of an upgrade scheme for non-seismic buildings using steel plate shear walls (spsw). the upgrade is carried out considering a probability-based drift-based criter...
متن کاملSeismic Behavior of Intermediate Beams in Steel Plate Shear Walls
This paper presents some preliminary results of an ongoing research whose objective is to investigate the seismic behavior of intermediate beams (i.e., the beams other than those at the roof and foundation levels) in multi-story steel plate shear walls (SPSWs). Of primary interest is the determination of the strength level needed to avoid the formation of in-span plastic hinges, a relevant prac...
متن کاملTOPOLOGY OPTIMIZATION OF PERFORATED STEEL PLATE SHEAR WALLS WITH THICK PLATE IN SIMPLE FRAMES
In this paper, topology optimization (TO) is applied to determine the form, size and location of holes for the special form of perforated steel plate shear wall (PSPSW). The proposed model is based on the recently presented particular form of PSPSW that is called the ring-shaped steel plate shear wall. The strain energy is selected as the objective function in the optimization. Simple Isotropic...
متن کاملComparison of plasticity and stiffness of steel shear walls with composite steel plate shear wall
The steel shear wall and composite steel plate shear wall is introduced in recent three decade and is considered and is spread rapidly. Composite steel plate shear wall which is made of a layer of thin steel sheet with coating of reinforced concrete in one or both sides of steel palate is considered a third generation of resistance shear walls against lateral loads that in addition to increasin...
متن کاملductility-based seismic design of steel plate shear walls: practical application using standard sections
over the past decade of extensive research works, the thin un-stiffened steel plate shear wall(spsw) has now emerged as a promising lateral load resisting system. considering thedemand of performance-based seismic design (pbsd) philosophy in current and futureseismic design codes, a ductility-based design was recently proposed for spsw systems withpin-connected boundary beams. however, the effe...
