A methodology of reliability-based optimum seismic design of building structures on the basis of seismic risk analysis as well as stochastic seismic response analysis is developed. by taking into account of the seismicity of a region as well as a prescribed time-period for use of the structure, design earthquakes for both the elastic allowable and elasto-plastic ultimate seismic design principles are determined in terms of spectral density function and duration of ground acceleration excitations at the site together with the associated reliability required in the stochastic seismic response analysis for the respective design principle. Under the assumption of high statistical dependence among the safety margin responses of the structural system to seismic excitations, an optimum seismic design. procedure of multi-degree-of-freedom structural systems, which is capable within the second order statistics of both safety-measurable responses and the corresponding capacities of structures, is formulated in the form of minimizing the ununiformity of component failure probabilities with the constraints of system failure probabilities for the two design earthquakes. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
