Under section “Loads”
For additional dead loads we will apply a uniform distributed load of 2.5 kN/m² on all areas. In every support axis we define a settlement wzz = 10 mm and save the loads within the load cases 51 to 53. For the temperature loads we generate 4 loadcases 81 to 84 containing the basic temperature loads
It will be helpful for most beginners like me to give more details in how to achieve these objects.
