Source Code
Synthesis of a time history to satisfy a shock response spectrum specification. The time history consists of damped sinusoids. This program is intended mainly for modal transient analysis.
(formerly known as srs_syn.cpp)
Generate time history from wavelet table.
Synthesis of a time history to satisfy a shock response spectrum specification using wavelets. This program is particularly useful for shaker shock testing.
(formerly known as jsynth.cpp)
Synthesis of a time history to satisfy a shock response spectrum using wavelets with zero time delay.  The resulting acceleration time history somewhat resembles an actual seismic waveform. quake_wavelet_synth.exe quake_wavelet_synth.cpp
Synthesis of a time history to satisfy a shock response spectrum using wavelets with random time delays. This program could be used either for shaker shock or for a modal transient analysis.
Synthesis of a time history to satisfy a shock response spectrum specification using wavelets including a specified ZPA.
