In general this is not true.

Let f1(t)=1 and and f2(t)=-1

rms(f1)=1

rms(f2)=1

rms(f1+f2)=0

Let f1(t)=1 and and f2(t)=-1

rms(f1)=1

rms(f2)=1

rms(f1+f2)=0

Just out of curiosity, if the signal is non-periodic, how did you determine how big a cycle is?

I did a lot of pulse counting work, they are random, just like current, it is not steady in microscopic level, we say it is 1A only because in average there are so many electrons part a point per second and we use that as the average current....Yes, current is a stream of electrons passing in a random rate.
