Abstract：Now manually arranging the seismic-isolation bearings is time-consuming and inefficient, so it^，s a good idea to develop a software for seismic-isolation bearings’ optimal arranging based on genetic algorithm. First, the calculation method and limit value of the eccentricity ratio are discussed. Secondly, the basic theory, accurate meaning, fitness function of the genetic algorithm are discussed. Thirdly, general development process of the software for seismic-isolation bearings’ optimal arranging based on genetic algorithm is displayed. Finally, the developed software is tested by a real seismically isolated building. It’s clear that with the help of the developed software, the eccentricity ratio can be controlled conveniently and efficiently. So this research can promote the application of the seismically isolated buildings and reduce the number of earthquake disasters.
Key words：genetic algorithm; seismic-isolation bearing; eccentricity ratio
