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.
