I am trying to apply an 80 degree thermal load to the upper surface of an RC Shell but it won't let me specify a temperature in the "surface > thermal loads" window. I can assign a gradient and apply it to the shell but no temperature.
Solved! Go to Solution.
Sorry for the late reply, I've tried these already... I'm designing a flat RC slab and the option to input a temperature is not available.
I do "load definition", trying both "live" and "temperature" but within both of these the program does not allow me to input a temperature, only a gradient as seen in the image attached.
I wish to apply a temperature of 80 degrees C to the top surface of the slab, I'm designing it within "Plate Design".
temperature gradient along an element's thickness , along local Z.
gradient value -> on top = +half of gradient value , on bottom = -half of gradient value.
So for a slab thickness 650mm where it is desired to have 80 degrees at the upper surface and 20 at the base.... I would specify a gradient of -60/0.65 = -92.31 oC/m and this will simulate the desired affect?
In such case you have to change structure type on Shell then:
if you consider assembling temperature as 0 deg then:
if you consider assembling temperature as 20 deg then (elements have already temp 20 deg):
What is the meaning of "assembling temperature" and what is the difference between assembling temperature and the value of "dT1" in the "thermal load 3p window" ?
