Temperature load in industrial halls

Temperature load in industrial halls

Temperature load in industrial halls

I am doing structural analysis of steel hall (80m x 20m x 8m) according to EC3.
I have applied temperature load and as results I get huge axial load in facade beams .
My first options was to put vertical bracing in first field but in that case I have huge axial force in whole length of facade beams and that is reason why I have move these bracing in middle.
What is your experience with temperature load? Are these forces real? EC1 explicit say to use temperature load. I am using Dlubal RFEM software.

RE: Temperature load in industrial halls

For steel exposed to weather, the expansion/contraction force is real. You shall consider add expansion joints to accommodate the change in length due to thermal effect.

Note the temperature to be used in your analysis is the temperature difference between the expected highest/lowest temperature in the project site less the estimated temperature during erection. Be conservative on either side - above or below the erection temperature (not a certain thing).
