FORMULAS FOR COMPUTING OF DEFLECTION AND FORCES IN THE TRUSS WITH ARBITRARY NUMBER OF PANELS

Abstract

The problem of the deflection of the flat statically determinate truss, having two supports and a com­plex lattice is solved in the system of computer mathematics Maple in symbolic form. The induction method and special operators receiving and solving recurrence equations are used to obtain the solution. The expression for forces in the most compression and tie rods are detected. Analyzed the distribution of material along the rods of the belts, girders and lattice, dependence of a deflection of the height of the truss and the number of panels. The asymptotic approximation of the solution for the case of fixed span length and a given load, uniformly distribut­ed over the nodes of the lower belt, is obtained
