SIMQKE-I

SIMQKE-I, latest version 2.7, is a comprehensive science tool developed by Prof. Piero Gelfi. Falling under the education category, this sophisticated software stands out in the science tools subcategory for its ability to generate statistically independent accelerograms, perform baseline corrections, and calculate response spectra. Users often recognize it by its aliases, SIMQKE_GR, or through its associated files, Profili_v6.exe, and SIMQKE_GR.exe.

The key feature of SIMQKE-I is its capability to generate ground motions that align with specified smooth response spectra. This is accomplished based on the relationship between response spectrum values for arbitrary damping and the expected Fourier amplitudes of the ground motion, as described by Vanmarcke in 1976. The program ingeniously synthesizes earthquakes by superimposing sinusoidal components with pseudo-random phase angles, which are then multiplied by a user-defined function representing the ground motion intensity variation over time.

One of the standout aspects of SIMQKE-I is the iterative capability to adjust the ordinates of the spectral density function. This iteration improves the agreement between computed response spectra and the specified targets. However, even without this step, the average response spectrum of simulated motions closely matches the smooth target spectrum.

SIMQKE-I supports a wide range of operating systems, including Windows XP, 7, 8, 10, and 11, making it accessible to a broad audience. Additionally, earlier versions such as 2.7, 2.4, and 2.3 offer compatibility and features for users with different needs.

For anyone involved in civil engineering or earthquake simulation, SIMQKE-I is an invaluable tool. Potential users can download the free version to explore its capabilities.
