Dissertation is devoted development of new spatial model of grillages of the reinforced concretes for determination of their tensely-deformed state and bearing capabilities taking into account physically nonlinear work of material at the action of the static loading. Grounded actuality, a scientific novelty and practical meaningfulness of work is formulated, its general description is given. The scientific task state is exposed, a purpose and tasks of researches is formulated.
On the basis of method of moving the matrix algorithm of calculation of the system of cross beams, including determination of inflexibility of stability to cracks and durability of normal cuts of beams of the reinforced concretes and diagrams a bend moment is curvature, is offered. Resulted foot-pace is iteration procedure for realization of nonlinear model of the reinforced concrete for the calculation of such constructions of the reinforced concretes: caissons without ceilings of beams, flights structures of road-transport bridges.
Verification of the offered method is executed by comparison of results of author with the known decisions and experimental information of other authors.
The considerable concentration of efforts is set in a vicinity of middle columns of the reinforced concretes caissons of uncuts and without ceilings of beams.
Creation cracks and non-linearity of deformation of the reinforced concrete results in the substantial increase of bendings and contracting efforts in grillages.
The developed method gives reliable enough results and can be used in the real planning of the considered constructions of the reinforced concretes .
Keywords: model of the reinforced concrete, grillage, method of moving, tensely – the state is deformed, bearing ability, foot-pace method.
