ON THE CHOICE OF THE LATTICE GIRDER

Abstract

The analytical solution to the problem of deflection of statically determinate flat truss with diagonal bars is obtained. The solution is compared with a similar of the truss with a triangular lattice. Solution is prepared in the system of computer mathematics Maple. The method of induction is used for generalization the solution to an arbitrary number of panels. The asymptotic properties of solutions are found. The formulas for forces in the most compression and tie rods are obtained.
