摘要
Methods, systems, and computer-readable media generate acceleration time histories. An initial acceleration history is applied to a response model with natural frequencies across a spectrum of interest to develop a displacement response. Low-frequency enhancement signals are determined by comparing the displacement response to a standard displacement response. The enhancement signals are combined with the initial acceleration history to develop a second acceleration history, which is applied to the response model to develop an acceleration response. High-frequency enhancement signals are determined by comparing the acceleration response to a standard acceleration response. The enhancement signals are combined with the second acceleration history to develop a desired acceleration history. Acceleration histories also may be created by adding random phase angles at various frequencies to an initial acceleration history in the frequency domain, which is then converted to the time domain and scaled to generate a low-correlation history.
