A structural reinforced concrete shear wall in a 5-story building provides lateral and gravity load resistance for the applied load as shown in the figure below. Shear can be used when referring to a lateral load or force that is applied during high wind events or earthquakes, but it is also more generally used to describe stress on a wall system that occurs due to an applied load. Shear walls are designed to resist lateral forces, such as wind or seismic, and transfer these forces to the component below them, which might be other shear walls, floors, foundation walls, slabs, footings or embedded columns. Kostem FRtTZ ENGINEERif~G LABORATOF?Y LIBRARY Fritz Engineering Laboratory. 2 shown above is based on the assumption that yielding at the assumed critical section occurs over a plastic hinge height of one-half of the wall length.
