According to aseismic design for a circuit breaker system, the system is confirmed safe if it withstands during a duration of three periods of sinusoidal ground acceleration with resonant frequency. Under this concept, optimal design procedure has been developed and optimization algorithm is presented. By using a simple structure composed of 10 members with two lamped masses as an example problem, the algorithm is verified by finding the optimal areas of members with stress constraints. ƒL�[ƒ��[ƒh�i‰p�j�F structural optimization,dynamic analysis,mass excitation,resonant frequency ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
