Abstract:

Steel plate shear walls (SPSW) are lateral load resisting systems that can be an alternative to other lateral load systems. The main advantages of slender SPSW consist of economy in steel weight due to thinner walls and less construction time compared to concrete shear walls . Furthermore, with appropriate design and detailing, SPSW systems may be classified as ductile systems. Previous studies have shown that the column demands in a SPSW are extremely large. Column axial demands result primarily from resisting the overturning moment and can be large for multi-story SPSWs. To reduce column demands in SPSWs some researchers disconnected steel plate from columns to eliminate pull-in forces. In this research a comparison study is done on the axial forces of columns of SPSWs. In the present study, eight SPSW models are analyzed and the results are utilized to discuss about differences in column forces, capacity and initial stiffness of the conventional steel plate shear walls and the new ones that steel plate is detached from columns called DSPSW. Results show thatdetaching steel plate from columns reduce axial forces in columns.
