Zusammenfassung:It is very important for structural design to estimate the response displacement of the structures for the input earthquakes. For that purpose, static analysis is to be used because of its simplicity and practicality though dynamic response analysis might be most suitable approach to prescribe the actual characteristics of structures. Present paper proposes the design load which is used in the static analysis and can approximate dynamic maximum response displacement of the objective structure. In order to predict such static design load distribution, genetic algorithm is utilized together with dynamic elasto-plastic analysis of simple models.
