  Shear walls are used in buildings to resist the lateral load induced during earthquakes. Shear walls generally have rectangular cross section with the high concentration of vertical reinforcement at the boundary elements. The use of conventional reinforced concrete shear wall in multistoried buildings is sometimes limited because of the high concentration of reinforcement provided at the boundary element. Composite steel-concrete shear wall with encased vertical steel sections provide good alternative. Composite steel-concrete shear walls are modeled as equivalent frame element and analyzed using a modeling software pushover capability. Comparative study indicates that presence of vertical steel sections significantly increases base shear and ductility.
