P-Wave Forcing Function

P-Wave Forcing Function

P-Wave Forcing Function

(OP)
I've got a situation where I am trying to model foundation motion from an adjacent foundation producing lots of vibration. Normally I disregard the P-wave input because it tends to be a very small fraction of the output (at the source) and it attenuates rapidly. But here it is too close to disregard. In the past, I've done this by (of course) having the foundation supported by springs......and the forcing function being sinusoidal (i.e. for the Rayleigh waves or S-Waves).

But for P-Waves, I'm not sure how to approximate them. My first guess would be a sinusoidal forcing function as well. But then again, I'm not sure that maybe a "saw tooth" or square wave might be more accurate.

Any ideas? Thanks.
