Brednyov A. Strength and stability of crack of reinforced concrete beams on inclined sections under the action of low-cycle loads

The object of researches is a concrete prisms and а reinforced concrete beams; a purpose is an experimental and theoretical explanation of influence technological damage of concrete on development of cracks and calculate the strength of inclined sections reinforced concrete members under the action of low-cycle loads; the methods are utilization of special and generally accepted methodics, theoretical analysis; results are development methods to calculate the strength of inclined sections of curved reinforced concrete members under the action of low-cycle loads with a new coefficient ?b4; a novelty is the influence of technological damage on physical and mechanical characteristics of concrete has been defined; Dependence of bearing power value of reinforced concrete beams of inclined sections under the action of low-cycle loads on technological damage of concrete; development a new value of coefficient ?b4, on saturation of samples by transverse and longitudinal reinforcement, concrete compression strength and technological damage of concrete; it is inculcated – at planning of reinforced beam constructions of complex of dwelling-house on Zatonskaya street – Krimskii boulevard; the sphere of the use is planning of beams constructions.
