:: Construction Schedule .: Stage Actions : Dynamic Calculation
Actions used for dynamic structural analysis are:
| Setting | Description |
|---|---|
| TInt | Full dynamic calculation in time steps. The time history calculation is performed as time integration over given time steps of a load case variable with time (e.g. Rolling Stock Analysis) |
| Eigen | Solution of the eigenvalue problem for a given reference load case. Results are n eigenfrequencies and eigenvalues (natural modes of vibration). |
| RespS | Seismic design - dynamic analysis in vibration modes (modal analysis) using response spectra (defined in ::Construction Schedule .: Load definition · Seismic ). |
| T2Resp | Calculation of a response spectrum (acceleration vs. frequency) from a time history function (acceleration vs. frequency). For accelerations and displacements. |
| Excit | Random analysis for excitation spectrum. |
| Wind | Calculation of wind buffeting (aerodynamic turbulence effects). |
| FFT | Fourier transformation of a given time history function (a table of time steps and values) to calculate it's frequency domain (intensity vs. frequency) |
Refer to the help texts of the individual actions for details.
