TR.32.6 Temperature Load Specification for Members, Plates, and Solids

This command may be used to specify TEMPERATURE loads or strain loads on members, plates, and solids; or strain loads on members.

General Format

memb/elem-list { TEMP f1 f2 f4STRAIN f3 | STRAINRATE f5 }


f1 The change in temperature which will cause axial elongation in the members or uniform volume expansion in plates and solids. The temperature unit is the same as the unit chosen for the coefficient of thermal expansion ALPHA under the CONSTANT command. (Members/Plates/Solids)
f2 The temperature differential from the top to the bottom of the member or plate (Ttop surface-Tbottom surface). If f2 is omitted, no bending will be considered. (Local Y axis) (Members/Plates). Section depth must be entered for prismatic.
f3 Initial axial elongation (+)/ shrinkage (-) in member due to misfit, etc. in length unit (Members only).
f4 The temperature differential from side to side of the member. (Local Z axis) (Members). Section or flange width must be entered for prismatic.
f5 Initial axial elongation (+)/ shrinkage (-) per unit length, of members only.

  1. It is not necessary or possible to specify the units for temperature or for ALPHA. The user must ensure that the value provided for ALPHA is consistent in terms of units with the value provided for the temperature load. (See TR.26 Specifying and Assigning Material Constants).

    If ALPHA was provided by a material name (STEEL, CONCRETE, ALUMINUM) then the temperature here must be in degree Fahrenheit units (if English length units were in effect when Alpha was defined) or degree Celsius units (if metric length units were in effect when Alpha was defined).
