Temperature loading - deviating from casting time temperature
Temperature loading - deviating from casting time temperature
(OP)
Hi people!
We have a new project coming up soon, external, open, concrete parking garage, flat slab system, supported on columns and walls.
Following my code on loading the structure with temperature loading I have following situation.
The garage will be cast during summer when the mean month temperature is 19C.
The mean winter temperature is around 5C.
The difference between tha casting temperature and minimum winter temp is the unifor thermal load wich is -14C nad will couse contraction in the structure.
Should shrinkage be superimpossed with this temperature difference?
In this case I have a uniform temperature load of -14C (as calculated previously).
Ive calculated shrinkage strain of the structure (slabs only) and for this case its around 250x10^-6.
Converting this to uniform temperature its like having a temperature drop of -25C wich will couse additional shrinkage.
Should these two values be superimpossed for getting the FINAL uniform temperature loading on the structure?
In this case this woulde mean an uniform tempeature loading of =-14-25=-39C?
