タイトル（英）：	GENERATION OF SIMULATED EARTHQUAKE MOTIONS WITH MULTIPLE DAMPING RATIOS USING GENETIC ALGORITHMS
抄録（英）：	A technique to generate simulated earthquake motions for structural design considering multiple damping ratios has been developed. Simulated earthquake motions whose response spectrum meet the target response spectrum with 5% damping ratio are often used for earthquake resistant design of structures. As 5% damping ratio doesn't fit facilities and pipes, the resultant simulated earthquake motions wouldn't meet these parts. This tech-nique can generate simulated earthquake motions that meet the target response spectrum with multiple damping ratios using genetic algorithms and pareto optimal method. Example simulated earthquake motions were generated to illustrate efficiency of this technique. Gen-erated motions fitted the target spectrum better than the motions generated by traditional sinusoidal wave superposition method. Pareto optimal set of simulated earthquake motions could enable structural designers to determine input earthquake motions reasonably.
