Some issues of calculation of complex rod and plate systems on an elastic base

This paper summarizes some issues of a new universal method for static calculation complex rod and plate systems on an arbitrary elastic base under the influence external load, when modeling with various models, ranging from classical Winkler model to combined Winkler-Kogan model. The relevance timeliness proposed work lies in fact that calculating structures have not yet been fully investigated there is no general approach their calculation. author knows works M. I.

Bosakov, which approaches used conduct research simple core structures, isolated foundation including mesh slabs, as well spatial monolithic foundations, system cross belts base. based mixed structural mechanics using functions medium relations Zhemochkin. To simplify these relations, determining coefficients canonical equations free terms connected plates, deflections plates normal pinched centre are used. For pivotally beams, it convenient introduce pinching unknown displacements at beginning or end each beam, frame rods-in nodal connections. numerical implementation performed Mathematica computer program.
