An efficient and systematic procedure is proposed for finding the optimal damper positioning to minimize the dynamic compliance of a 3‐D shear building model. The dynamic compliance is expressed in terms of the transfer function amplitudes of the local interstorey drifts evaluated at the undamped fu...
