-----------------------------------------------------------------------------------------------------------------------------------------This is my code for opensees, i would like to perform a parametric analysis for it so how can i vary my load "p" between 0-120 instead of only analysing it for P = 100.

Use for loop (In OpenSees code)
for {set p 1} {$p <= 120} {incr p 10}
{
