Le M. Influence of local damages of a concrete cover in the compressed reinforced concrete elements on stress and strain state of the fixture

Subject of research - compressed stiff reinforced concrete elements having partial damage of a concrete cover. The purpose-definition of load-carrying ability of the weakened elements thus. The model of the compressed reinforced concrete element as a built-bar with elements of rigidity in a contact zone is developed. By results of theoretical and experimental researches the design procedure of load-carrying ability of such damaged elements is developed. The new experimental data of deformations of the fixture and concrete are received at compression of specimens by loading applied to concrete with the help of the modern equipment. The introduction of results is carried out in JGBK-1 in the city of Kharkov and at reconstruction of buildings and structures in development Kharkov PromstroiNIIproject.
