Nonlinear analysis of a crossing-beams system on an elastic with usage of the Mathematica software

In this paper, the authors consider method of calculating an infinite system cross beams on elastic base by variationaldifference method. The is most often modeled as shallow strip foundations for buildings various functional purposes. variation-difference one numerical and analytical methods building structures, it based variational principles Ritz-Timoshenko minimum total potential energy entire according to Lagrange principle, also close real operating conditions foundation – base. A single-layer isotropic artificial was used in work, layer limited thickness. algorithm nonlinear calculation use iterative solutions. physical nonlinearity material reinforced concrete taken into account through asymptotic dependence “Moment-curvature”. Numerical approbation results calculations carried out using MATHEMATICA software package.
