heat difference calculation

[dabanlio]

Hello, I have some questions about how the heat difference calculation works in the program. For example, I want to calculate the case where the structure is exposed to a temperature difference of 10 degrees. Should T1: 0 and T2 : 10 be entered in this case? Or are both values independent of each other? or if T1:-10 and T2: 10 are entered, will the structure be calculated based on a total temperature difference of 20 degrees. there are also cases where the heat difference calculation is not used in capacity controls and concrete design, or I could not find it. what is the reason for this? thanks.

In the heat difference calculation, T1 and T2 represent two different loading conditions. It is independent of each other. One loading for T1 temperature value... Another loading for T2 temperature value. Each installation will enter the most unfavorable combination. With normal build combinations: G+1.2Q + 1.2T1 and G+1.2Q becomes +1.2T2. As a result of the calculation, you see T1 and T2 loads as element end forces.

in addition, there are cases where the heat difference calculation is not used in capacity controls and concrete design, or I could not find it.

The heat load may not have been selected as the most unfavorable load combination in the design. (The heat load may not have been the most unfavorable) You can examine the heat loads manually in the capacity diagrams.
