My doubt is related to calculation of support forces in Caesar.

Ref: Eqn.(9) and Eqn. (10) of B31.1 2007

Let us consider an hypothetical case:

At a particular support,

Dead weight, WT= 2000 N

Relaxation (cold spring), C =1 (100%)

Eh/Ec = 0.9

Reaction for full expansion range, R = -1000 N

So,
Rh=(1-2/3)(0.9*-1000) = -300 N

Rc= -CR= -1*(-1000)= 1000 N

WT+Rh= 2000+(-300)= 1700 N and

WT+Rc= 2000+(1000)= 3000 N -------- (a) .

Please correct me if I am wrong but, for this case, Caesar will give output as:

WT= 2000 N
OPE= WT+R = 2000+(-1000) =1000 N
EXP= -1000 N
So, MAX= 2000 N -------- (b)

Shouldn't Caesar consider 3000 N (as per eqn.(a) above) as the MAX force possible instead of 2000 N (as per eqn.(b) above)?

Also, isn't EXP= WT+Rh the correct choice rather than EXP= WT+R?
