Shear Wall Design
Shear walls are vertical structural elements that resist lateral loads (wind, seismic) through shear and flexural action. They provide stiffness and strength to buildings. Shear walls are designed for in-plane shear and bending. Boundary elements (confined regions at wall ends) are required when wall stresses exceed certain limits. Coupling beams connect multiple shear walls to improve lateral resistance.
