Dear all!! As far as I know B31.1 (so CAESAR) uses cold modulus of elasticity when calculating pipe stress in all cases (suatained, exapansion, occasional). But what happens when calculating reactions on supports? B31.1 in section 119.10.1 states that reactions in hot condition may be reduced by the ratio between hot and cold modulus of elasticity. When CAESAR provides reactions in opearating condition, how does it manages modulus of elasticity? Does it use the hot or cold one?

Thanks for any help
