The efficiency of seismic isolation application considerably depends on the right selection of the damping parameters. As a rule, the mathematical model of the seismic isolation system (SIS) is nonlinear. In a nonlinear model, power characteristic of the SIS elements depends at least on three parameters, which significantly complicates the solving of the optimizing task. Therefore, it makes sense to linearize the initial dynamic task, as in the linearized task it is not difficult to create an algorithm of the damping optimum parameter search (dimensionless coefficient of damping). The present article is devoted to a technique of searching for the elastic plastic dampers optimum parameters in SIS by means of the linearized dynamic model.
