Free software for earthquake engineering and structural dynamic
RespSpectra is an OCTAVE code, which enables the calculation of the response spectrum of earthquake acceleration time-histories.
To run RespSpectra.m:
- Run Octave
- Type RespSpectra and Return
- Answer the questions
Informations and recommendations
- Since RespSpectra runs with the Central Difference Algorithmus, the upper frequency corresponds to 1/(time interval * pi).
- RespSpectra calculates the spectral values for 200 frequencies with an uniform logarithmic distribution. The number of frequencies may be changed by changing the variable nf.
