Savchenko A. Joint work of beams and longitudinal girders in composition of the overlapping floor.

Object - precast concret modular and modular-monolithic overlaps. The purpose - development of a technique of account of modular and modular-monolithic overlaps in view of space work of plates with one another, as well as modular plates with longitudinal girders, at change toughness influence. Methods - numerical - analytical method, method of final elements, experimental researches on a fragment of overlapping. Equipment - indicators of a hour type, hydraulic presses, gaping machine. Theoretical and practical results - received results of researches and techniques of account permit more precisely and economically calculate and to design modular and modular-monolithic overlap. Novelty - dependence of influence toughness influence longitudinal girders on joint work of modular plates; a technique of account of efforts of interaction between modular plates and longitudinal girders is developed on the basis of the theory of compound rods, which takes into account not only transverse shearing, but also vertical making by these efforts; the numerical - analytical technique of account of efforts in overlaps, monolithic plate of which hinge leans on modular beams; results of experimental - theoretical researches of a stained deformed condition of modular overlaps in view of their space work. Degree of introduction - survey of a bridge through r. Strelka in the Sumy, project of reconstruction Management of urban development in the Uman. Branch - building.
