Gap unit load case

Hi,

I am modelling force deflection curve for gap element. Unit load case needs to be applied on the gap element in the SACS model. I was wondering if there is easy way to apply. 

LOADCNDA01
LOAD X SA01101L 1.0 MEMB CONC DUM
LOAD X 101LSA01 -1.0 MEMB CONC DUM

Your advice is appreciated.

Thanks,
