Analyze SDOF random vibration response in real time. Compute response spectrum, RMS, and 3-sigma values from your input PSD with adjustable 3-segment profiles.

Real-time seismic design simulator: compute base shear, period, and story drift. Adjust building stories and site class for instant analysis.

Seismic design spectrum calculator for building natural period and soil type.

Analyze seismic isolation performance by adjusting building mass, stiffness, damping, and soil type.

Seismic Response Spectrum (Sa/Sv/Sd) Simulator compares how environmental or chemical-process balance and operating margin shifts as the main assumptions change.

Interactively compute design response spectra (Japan Building Code / ASCE/SEI 7 simplified model) and SDOF seismic response. Visualize Sa, Sv, Sd spectra in real time.

Shock Response Spectrum Simulator: Numerically integrate the response of a single-degree-of-freedom (SDOF) system to a half-sine shock pulse.
