Abstract
The problems of calculation of compressed and bended steel reinforced concrete structures in the retained formwork were considered. Apart it’s necessary to consider the questions which are related with calculation tube concrete tube structures. As the role of steel tube in the tube concrete reduced mainly to reduced of transversal expanding of concrete core at the element compression, but from the theory of concrete strength it’s known, that with the increasing of transversal compression the strength of concrete may increase significantly, then a major role in bearing capacity tube concrete element must perform work steel pipe in the transverse direction. The method is developed in the compressed elements from steel i-sections with lateral cavities, fulled by concrete. The method of calculation by the deformed scheme is more accurately express the real picture of elements deformation. The method of calculating of bending reinforced concrete elements in non-removable formwork to a transverse force. The conclusion of the feasibility of using the calculated deformation model that best corresponds to the real work of load bearing structures was made. The program of calculation of the computer, which provides a satisfactory convergence with experimental data is composed by the developed methodology.
