THE ANALYSIS OF NICE CALCULATIONS FOR DISPLACEMENTS OF REGULAR JOINT-AND-ROD STRUCTURES

The exact analytical expressions for deflection of plane truss structures of various kinds are presented. Deflection of trusses calculated by the formula of the Maxwell-Mohr on the assumption of elastic elements of its work and with the help of the method of induction on the number of panels is given. A comparative analysis with known solutions is given too. We study the quantitative and qualitative features of solutions. Identifies characteristics and limits on the number of panels characteristics are shown. Research carried out with the support of the computer mathematic program Marle in symbolic form. For comparison, solutions and test were made with using a multifunctional software package Lira, which is intended for the de- sign and calculation of building and engineering structures
