Majority of shear wall buildings in the existing building stock have been constructed prior to introduction of modern seismic codes. Field investigations after major earthquakes showed that such buildings were heavily damaged or even collapsed due to poor design and construction, particularly because of inadequate boundary reinforcement and detailing. To ensure sustainability of buildings even after strong ground motions, seismic rehabilitation and retrofit of existing buildings are important. Efficient rehabilitation and retrofitting can better be achieved by analytically modeling expected behavior of existing buildings as close to accurate as possible. Behavior of structural walls under lateral cyclic loading can be best characterized by shear strength and deformation capacity (or ductility). Many studies have been carried out to examine shear strength of reinforced concrete shear walls, which have led to development of shear strength equations to be used in current seismic codes. However, studies that investigate deformation capacity of reinforced concrete shear walls remain relatively limited. This study focuses on assessment of deformation capacity of reinforced concrete structural walls as well as influence of various key parameters (e.g. shear span ratio, axial load, reinforcement ratios) on wall ductility. To achieve these goals, a detailed wall test database consisting of 172 specimens was assembled. Statistical studies and linear regression analyses were carried out on this database to determine parameters that affect ductility of shear walls controlled by different failure modes. Based on statistical studies, mean values of curvature ductility were obtained as about
