Components of numerical experiment system have been developed for optimization of passive control and isolation devices. This sytem consists of a consitutive model and its identification method of steel material under cyclic deformation, a probabilistic approach for obtaining accurate approximate optimal solutions within small number of analyses, and a probabilistic method for estimating bounds of parameters and responses of buinding frames. It has been shown that the energy dissipation and deformation capacities can be improved by optimizing the shape of shear panel damper. Furthermore, it has been shown in the analysis of base-isolated building that the local responses of the rubber bearings can be evaluated in detail using a high-performance finite element analysis.
