Insuring structural system ductility is a main factor justifying the reduction made on design
earthquake forces. Reinforced concrete shear wall is one of the most important systems used for
earthquake resistance of buildings. In this research, many
factors affecting curvature ductility of
shear wall sections are studied. These factors are reinforcement ratio, reinforcement
distribution (uniform and concentrated), axial force level, section length, and material
properties. Results show that increasing reinforcement ratio, will reduce ductility in case of
uniform reinforced shear walls, but it stays stable in case of concentrated reinforcement. As for
axial force level, curvature ductility becomes lower as axial force increases and almost
diminishes when it becomes more than half ultimate axial force bearing capacity.
