Stability of elements require determination of their dimension, such that
the resulting displacement under static or thermal loads are acceptable.
Those elements have to resist the applied loads so that the structure or any
element does not loss c
onstancy. The most important criteria for stability
is represented via element curvature under the influence of load, that load
is of any type or in any position. Therefor this paper presents derivation
of a theoretical equation to calculate the deflection generated from
heating variation between the top and bottom surface of simple steel
beam, by means of heating transfer expression.
