Abstract

There is disclosed a seismic response control method for a structure, comprising the steps of installing a seismic response control device in a structural component of stiffness K.sub.f ; and controlling a characteristic of story restitutive force based of story restitutive force Q (=Q.sub.s +F) given as the sum of restitutive force Q.sub.s of the structural component installed with the seismic response control device and force F generated from the seismic response control device so as to maintain or vary the characteristic of story restitutive force, which is shown on a coordinate plane as the relation between amplitude D(t) and story restitutive force Q(t) of the structural component portion, in the specific form, in response to the kaleidoscopic state of vibration. The seismic response control device is controlled efficiently with a sensor for measuring a state value of a device part and a simple configuration on microprocessor level.
