The current seismic design parameter demands less distortions and preservation of nonstationary characteristics and phase angle in design acceleration time histories. This research presents an improved iterative spectral matching method in the time domain for generating acceleration time series compatible with the target design spectrum with high frequency enrichment. A modified correction function in time domain referred as windowed adjustment functionto modify the selected initial input ground motion is proposed.
