タイトル（英）：	APPLICATION OF GENETIC ALGORITHMS TO THE SEISMIC DESIGN BASED ON THE INTERACTION PIER AND BEARING
抄録（英）：	This paper presents an analytical study on the application of genetic algorithms to the seismic design of the road bridges. After the Hyogo-ken Nanbu Earthquake, Japanese design code of road bridge was revised and current design code requires the consideration of the elastic-plastic behavior. Thus, it is very difficult to control design process and so it takes quite long time to get the results which satisfy the designer's concept. Therefore, an application of Genetic Algorithm to ultimate strength seismic design is proposed and examined the effect of it in this study. In this analysis, the reinforcement ratio of RC piers and the stiffness of bearings are decided on the conditions that the load shearing ratio of each bearing is the same as the prescribed value and the natural period of overall motion becomes longer in order to decrease the seismic load. It is confirmed that this numerical analysis by Genetic Algorithm give good solutions with a little trial, and it is regarded as very useful method for the ultimate strength seismic design of road bridges.
