Steel-reinforced concrete elements strengthened by the anchoring method

The object of research is steel-reinforced concrete elements in which various anchoring methods provide the joint work of concrete and steel. Method. The results of experimental studies of the bearing ability to shift the units of a galvanized sheet profile with a reinforced concrete structure concerning the beams of the Marco-UNIVIVERSAL system and the development of a methodology for the calculated determination of the limit voltages in the designs of thin-leaf rolling. Four methods of connecting rental sheets with concrete design have been implemented: without special anchors due to the adhesive ability of cement stone; with the help of frozen ones at the stage of manufacturing the design of anchor bolts; with the aid of steel dowels scored in concrete durability; With the help of bends inside the concrete block sections of the sheet rolling profile. Regarding shifting efforts, at the time of the destruction of the compounds, the maximum stresses are determined in the profile sheets, recommended as calculated resistances. Results. Conclusions have been drawn about the most optimal ways of surveying the sheet profile in concrete from the standpoint of its most complete inclusion in the work as part of steel-reinforced concrete structures, as well as considering the manufacturability of the installation of anchor devices at the construction site.
