Special Reinforced Concrete Shear Wall Design

Special reinforced concrete structural walls are walls that have been proportioned and detailed to meet special code requirements for resisting combinations of shear moment and axial force that result as a building sways through multiple displacement cycles during strong earthquake ground shaking.
