An approximate method for the dynamic earthquake analysis of coupled shear walls within the framework of design response spectra is proposed. The first three modes of vibration are considered and the dynamic loading associated with each is assumed to be represented by the corresponding mode of a vibrating cantilever. Based on this approximation, the natural frequencies, deflection, internal forces and moments are computed and the design parameters of interest are presented in design chart form. A numerical example is worked out in detail to illustrate the use of the design charts. The contribution of higher modes is examined and the need to consider their effect is demonstrated.
