System Temperature

When the temperature of the entire structure varies from an initial (reference) temperature to a set temperature (final temperature) for thermal stress analysis, enter the final or system temperature. Modify or delete the previously entered final temperatures.

The thermal variation load analysis is carried out for all the elements in MIDAS/Gen. The temperature change renders thermal strains and consequent internal forces in members.

Where, is the linear thermal expansion coefficient entered in "Material". T1 is the initial temperature (refer to "Structure Type") and T2 is the final temperature of the structure. The final temperature can be assigned to the total structure. Different final temperatures (refer to "Nodal Temperature") may be assigned to different parts of the structure.

From the Main Menu select Load > System Temperature.

Select Static Loads > Temperature Loads > System Temperature in the Menu tab of the Tree Menu.

Load Case Name

Assign the load case name. Click to the right to enter additional load cases and modify or delete existing load cases.

 

Load Group Name

Select the desired Load Group that will include the entered System Temperature data. Select "Default" if a Group assignment is unnecessary. Click to the right to add, modify or delete Load Groups.
