Seismic Design of Cast-in-Place Concrete Special Structural Walls and Coupling Beams: A Guide for Practicing Engineers. NEHRP Seismic Design Technical Brief No. 6
The basic structural elements of an earthquake-resistant building are diaphragms, vertical framing elements, and the foundation. In reinforced concrete buildings, the vertical elements are usually either moment-resisting frames or structural walls (sometimes referred to as shear walls). 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. Special proportioning and detailing requirements result in a wall capable of resisting strong earthquake shaking without unacceptable loss of stiffness or strength. This Guide emphasizes the most common types of special reinforced concrete structural walls, which use cast-in-place, normalweight aggregate concrete and deformed, non-prestressed reinforcement. Wall configurations vary depending on the application, and may include coupling beams. Building codes permit the use of special walls using precast concrete, lightweight aggregate concrete, or prestressed reinforcement. Building codes also permit the use of ordinary cast-in-place structural walls in buildings assigned to Seismic Design Category A, B, or C, and intermediate precast walls in some buildings assigned to Seismic Design Category A, B, C, D, E, or F. The interested reader is referred to ACI 318 for specific requirements for these other systems, which are outside the scope of this Guide.
