Abstract In a coupled shear wall structure the external lateral load generates flexure, shear and axial load in the walls, in addition to compression and bending with high shear stresses in coupling slab. Due to bending stiffness of the slabs the walls do not act as independent simple cantilevers. In this way the slab, in conjunction with the shear walls, provide stiffer and stronger structures to resist lateral loads. Some part of the slab which is called effective width acts as a lintel beam. The effective width of slabs coupling shear walls have been studied by many researchers. Many parameters affect the effective width. The shape of the wall section, size of opening, dimensions of slab and wall section, unsymmetry of walls, effect of twisting moment and the properties of the slab meterial are the main parameters. |
