modulus of elasticity for tempreature effect
modulus of elasticity for tempreature effect
(OP)
Hi all
i have a builing 100 Ms lenght with no Expansion Joint, where carrying out tempreature analysis is a must, i carried out the analysis for floor assuming it is restrined by columns above and below , using modulus of elasticity as per ACI , my question is shall i use any reduced value of modulus of elasticity as this tempreature effect will happend on a long time interval?

This effect is carefully considered for post tensioned segmental bridge construction as time dependent behavior is very critical. For reinforced concrete structures, this effect is hardly considered. ACI-318 prediction for E is well enough.

but do you think i should use the value mentioned in ACI-318 in slab tempreature analysis or i can make some reduction to it?
