Re: Differential temperature effect

[Subject Prev][Subject Next][Thread Prev][Thread Next]


This is a little off topic, but if your 300C is above 0C I would be worried about the long term effects of the elevated temperature on the concrete.  I can not help much with SAP but I do remember you have look closely at which type of element you pick.  I believe one will allow temperature gradients along the length of the element and another allows a temperature gradient across the element.

Does anyone of you have any experience in designing a reinforced concrete
having differential thermal conditions with SAP2000 software? I'm just
trying to design a complicated RC structure with nearly 300 C differential
temperature and I don't have the chance of insulating it due to the process
of the structure.
I have tried to obtain the bending moments by means of SAP2000 software but
I'm not able to satisfy the results given in some text books such as "theory
of elasticity" by Timoshenko.

Any comment would be appreciated.
