Analysis of Shear Walls under Compression and Bending

Design of shear walls is a complex procedure, especially if the cross section of the shear wall is not regular in shape. Shear walls are usually treated like cantilevers fixed at the foundation level. Normally, lift wells are designed as shear walls. The design of shear walls takes horizontal forces into account by shear and bending. Design for shear in the walls can be managed by computing the shear stress distribution over the cross-section and reinforcing appropriately. However, published literature is not available that would give the interaction of axial compression and bending moments on the section. This paper presents a methodology developed for generation of interaction diagrams for shear walls, thereby enabling a more accurate description of the capacity of the shear wall cross section under the effect of axial compression and lateral bending.
