This paper describes an analytical method for the optimum design of R/C frames according to the "Shin-Taishin" design metnod. The design process are consist of two parts, that is, the strength design and the stiffness design of frames. In the strength design allowable stress design method is applied for the cross-sectional design of each member, and first and second design of frames are carried out according to the "Shin Taishin" design method. In the stiffness design the dynamic plastic relative story displacements are controled in optimization procedure and they are estimated based on the modal analysis, RMS method and the plastic displacement spectrum. The plastic displacement spectrum which consider responses by the degrading tri-linear model is predicted from the elastic displacement spectrum. The minimum weight design of two types of R/C frames are carried out by the proposed method, and the resuits are discussed.
