     appropriate effects of composite sections on strength, stiffness and ductility of the structures has led to increasing research on advantages of using composite columns in steel plate shear walls (spsw) as a lateral load resisting system and its adequate design criteria. the current research was carried out to study the effects of composite columns as vertical boundary elements on seismic behavior of spsws by utilizing numerical models based on finite element method. several models were chosen to include shape and type of column sections, they include : (1) h-shaped steel section , (2) h-shaped steel section with concrete cast between the flanges , (3) square-shaped steel section and (4) square-shaped concrete filled steel section. beam to column joints were assumed as moment connections. the results were compared in parameters such as stiffness, load carrying capacity and energy dissipating capability. it was concluded that using composite vertical boundary elements can considerably improve energy dissipation capacity, stiffness and strength of spsw systems.
