Artificial ground motion simulation with target response spectrum being compatible is a significant challenge for structural seismic design. In the presented scheme, two major modifications are implied on conventional frequency domain methodology as to realize automatic recognition of stubborn points in iterative process and eliminate them by handling multiple control points in frequency domain. The proposed methodology is evaluated by numerical simulation with the target response spectrum from Chinese Specification for Seismic Design of Highway Bridges compared with conventional Stochastic Method. The result shows that the presented scheme enables to recognize stubborn points and eliminate them in iterative process as it is designed, and the fitting accuracy is improved considerably. The scheme is verified reliable to generate input ground motion candidates as a reference for engineers to conduct seismic dynamic analysis.
