“…Some prerequisites for calculation were used on the basis of the assumptions of the calculation, which are set out in the provisions of the current norms [1,2,3], other ones were proposed by the authors for the first time. Below are the calculated analytical dependencies for solving the problems of checking the strength and selection of the section of the SRSIP (rigid reinforcement) of the normal section of the bending SRC element, which was obtained as a result of numerical solutions [7,8,9].…”

(9) Optimum sectional area SRSIP (А а ) of the SRC element of rectangular section is determined by dependencies (3), (4), (9), preset by the initial values: beam section dimensions h, b and С z ; strength characteristics of concrete and steel: Е с , Е а , ε сu and ε au ; relation of both heights section SRSIP and element: Δ h =h a /h. Optimum sectional area SRSIP (А а ) of the SRC element with a concrete top shelf (Case I-B) is proposed to be determined by the following dependencies:…”

Methodical foundations for calculating the strength of normal sections of various types of steel-concrete bending elements are proposed, which allow calculating in dependence on the stress-strain state (SSS) at the moment of destruction of its components (concrete and structural reduced steel profile). The basis of the calculation allows solving two problems: the problem of determining the optimal section of reduced structural steel profile (RSSP), which reinforced the section of steel-concrete bending elements; the task of verifying the load-bearing capacity of a normal reduced section of various types of steel-concrete bending elements.

In this work the experimental research cycle is described. This cycle is an affect studying of the most widespread concrete defect types, such as concrete core weakening is an inclusion of the "weak" concrete, the presence of emptiness, concrete heterogeneous by the height. The research of the manufacturing conditions affect of combine concrete core structures and the elements of physical and mechanical characteristics changing are on the experimental research base. On the researches testing base of samples with special form and given sizes the concrete strength value is appreciated. The different variants of strength decreasing on the researched element height are analyzed by the conducted testing results of the steel reinforced concrete structures. As a result of the conducted tests, the work conditions coefficient and the steel reinforced concrete elements concreting technology were formulated.

“…The use of composite steel-concrete in composite cable space frame structures provides the opportunity for efficient and rational use of the strength properties of the most common building materials [12]. It is advisable to use columns of steel concrete composite tubular columns with centrifuged cores as abutments [13,14]. The characteristic feature of cable elements is their considerable deformability compared with rolled sections [15].…”

The article presents experimental study results of the deformation state of composite cable space frame structures, including composite steel-concrete structures. Composite cable space frame structures are three-dimensional roof framing of long-span buildings. The designed constructions are a new type of roof framing structures and consist of typical composite steel-concrete modules connected with steel cable elements. The operation of composite cable space frame structures under load is characterised by geometric nonlinearity. The aim of the research is to study the deformation state and changing the geometric shape of experimental structures under the influence of external load. The technique of studying the deformation state of the composite cable space frame structures is based on the principles of digital photogrammetry. At the limit state the composite cable space frame structures change their regular shape. In this case, the central vertical points get the greatest vertical displacements, and the displacement value decreases closer to the supports. It is defined that the investigated construction has demonstrated combined action of all its components during the test, which indicates its effectiveness. The application of the photogrammetry method made possible to determine the moment of reaching the limit state of the composite cable space frame structures concretely.
