Before defining temperature loads, keep the following in mind:
- Diamonds assumes that the default temperature of the structure is 20°C.
- The temperature you define is an increasing or descreasing of this 20°C.
- A gradient of for example +50°C, is translated to a load of +25°C at the top of the section and -25°C at the bottom. A gradient of -50°C, is translated as a load of -25°C at the top of the section and +25°C at the bottom.
Some examples:
- Example 1: The desired temperature at the top of a cross-section is
and the desired temperature at the bottom is
.
- Calculate the temperature difference between desired temperatures and default structure temperature (20°C)
