«G-Frc»: Calculation of the Jet Flow parameters and Fluid Flow Reaction Forces and resulting from the High Energy Pipe breaks

G-Frc is software for evaluation of the reaction forces exciting the high energy piping due to a release of the medium from a circumferential or longitudinal break. The program also allows assessing an impact of jet flow on the surrounding structures which are inside the zone of the jet expansion. Jet impact includes excessive pressure, temperature and wetness.

«CVSpec-TH» program is intended for developing and processing data used for seismic input in form of generated accelerograms and seismic response spectra.

Seismic design common practice assumes use of response spectra as input data for seismic loads. Such approach is justified in connection with Response Spectrum Method calculations. However some tasks require considering different nonlinear effects or non-proportional damping. In such cases Time History Analysis method is applicable for solving of the structure motion equations in the time domain. In that case seismic input is represented by an acceleration time-dependent record, called accelerogram or time history. The program is equipped with all necessary options for handling the Response Spectra: developing of Response Spectra from the Accelerograms according to the given set of damping and vice versa; scaling; interpolation of accelerations for given range or set of frequencies; interpolation of accelerations for intermediate values of damping; mutual recalculation of accelerations/velocities/displacements spectra; enveloping; statistical operations; options required by different Regulations.
