5.32.6 Temperature Load Specification for
Members, Plates, and Solids
Purpose
This command may be used to specify TEMPERATURE loads or
strain loads on members, plates, and solids; or strain loads on
members.

f
1
= The average change in temperature (from ambient “stress-
free” temperature) in the member/element 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)
f
2
= The temperature differential from the top to the bottom of the
member or plate (T
top surface
-T
bottom surface
). If f
2
is omitted, no
bending will be considered. (Local Y axis Members/ Local Z
axis Plates). Section depth must be entered for prismatic.
f
4
= The temperature differential from side to side of the member.
(Local Z axis) (Members only). Section or flange width must
be entered for prismatic.
f
3
= Initial axial elongation (+)/ shrinkage (-) in member due to
misfit, etc. in length unit (Members only).
See Section
1.16.6
f
5
= Initial axial elongation (+)/ shrinkage (-) per unit length, of
members only.
