Gasenko A. Reliability of Steel-concrete Composite Structures of Channels with Account Maintenance Damages.

Object - compressed steel-concrete composite elements from channels; the purpose - development of a technique of definition of reliability and bearing ability compressed steel-concrete composite elements with damages and defects and their units from channels; methods - experimental research methods of research of the is intense-deformed condition and bearing ability, methods of building mechanics, mathematical statistics, the theory of probability; novelty - is advanced a technique of experimental researches short steel-concrete composite elements from a metal environment from the channels; for the first time it is developed, experimentally and it is theoretically investigated new unit of frames from channels with use steel-concrete composite elements; The technique definition reliability (namely definitions of the characteristic of security of bearing ability) steel-concrete composite elements from channels at a stage of their operation in view of corrosions damages has received the further development; for definition of bearing ability and the characteristic of security of bearing ability compressed steel-concrete composite elements from channels in view of corrosions damages of a metal environment and local indulgences of a concrete kernel; a degree of introduction - on 5 objects of city of Poltava and the Poltava region; industry - is building.
