Abstract

This paper studied acase of reinforced concrete columns in an existing hospital building before and after applying earthquake loads and strengthening the building by adding RC Shear Walls (RCSW) and Steel Plate Shear Walls (SPSW).The objectives of this paper are to study the effects of using steel plate shear walls and RC shear walls with deferent thicknesses as retrofitting techniques and compare between the influences of the two approaches in reducing bending moments in the building columns. One typical model was selected from an existing RC hospital building, as a case study. The analysis of the building was carried out using SAP2000 FEA program and the 1997 Uniform Building Code (UBC 97). The retrofitting of the building was carried out by two techniques .Firstly, using SPSW with thicknesses of 5mm,10mm, 15 mm, and 20mm. Secondly, using RCSW with thicknesses of 10 cm, 15 cm, and 20cm. The building was analyzed before and after the consideration of earthquake loads applied in two directions XX and YY. The 24 columns analyzed in this paper resulted in reducing the moments by 57%, 60% and 61% by using RC shear walls of 10 cm, 15 cm and 20 cm thick respectively. On the other hand, the moments were reduced by 16%, 25%, 31% and 36% when using steel plate shear walls of 5 cm, 10 cm, 15 cm and 20 cm thick respectively. It can be observed that SPSWs showed a good effect in reducing bending moments at the building columns.
