Abstract
A method based on the continuum approach is presented for analysing the static response of multi -stiffened coupled shear walls, supported on flexible or rigid foundations, subjected to typical horizontal loads. The effect of the stiffening beams, one each at the top and bottom of the structure and two more at arbitrary intermediate levels of the walls, on the structural behaviour of coupled shear walls is investigated. The results of the investigations for a representative coupled shear wall system based on rigid foundation and a typical structure based on deformable foundation demonstrate that considerable structural benefits can be achieved by incorporating stiffening beams into coupled shear walls. The optimum positions for inserting one or two intermediate stiffening beams are discussed.
