We
have found the exact analytical expressions for the optimal geometry
and minimum mass of a diagonal truss beam made of a material with
properties of linear creep. We have derived simple analytical
expressions for the deflection of the optimal weight of the truss. The
deflection of the truss was calculated by the Maxwell  Mohr formula.
We found solution generalizations for any number of panels by
induction. The research was carried out with the support of the Maple
computer mathematics system in symbolic form. The multifunctional Lira
software package intended for the design and numerical calculation of
buildings and engineering structures was used for comparing and testing
the solutions.
Key words:
