The present study considers the free vibration analysis of stiffened multibay
coupled shear walls on elastic foundation. The connecting beam properties and the
thickness of the wall may be varied in a special manner. Continuous connection method
(CCM) is employed to find the system stiffness matrix. The system mass matrix is
found with the lumped mass assumption. A computer program has been prepared in
MATHEMATICA computer algebra system and some sample problems have been
solved. The results obtained using the foregoing program have been compared with
those obtained using SAP2000 structural analysis program, ending up with a good
match.
