I’ll suppose that at 4AM everything is at the same temperature (air and structure), and after that I’ll change the air temperature during the next 24h. I think that if there’s a mistake at the initial temperature of the elements, it will be regulated in less than 24h…
Thank you for your answer ione !
Actually I don’t know the surface material temperature… I have a table with the air temperature every 10 minutes in 24h. The goal of my analysis is to get the variation of the temperature inside the bridge during a day.
With these results I’ll be able (I hope...
Hello everyone,
I’m working with temperature loads on composite bridges (steel-concrete) and I have modelled one half of the cross-section with 2D elements (plane55) to analyse the convection at the outside lines. I had some problems with the film coefficients (free convection) and I posted my...
Thank you for your answer IRstuff.
Finally I applied only one film coefficient for both materials!
I’ll create a new thread at the Ansys section with a link for this one to see if I can get any help with the rest of the modelling!
Thank you!
I’m currently working on the analysis of the propagation of the temperature inside a composite steel-concrete bridge cross-section (when the air temperature is variable).
For this, I put myself into Ansys for the 2D thermal modeling of a symmetric cross section (two steel I-beams under a...
