Ductility in reinforced concrete beams

Using at high resistance concrete is increasingly increasing today. Using of HSC concrete in pillars leads to decrease in concrete cross section, its creeping, and reduction of secondary anchor; but using of it in bending members such as beams and pillars under bending leads to increase of the durability of the sections. Shrinkage of material is one of the most important issues that it will be taken in to consideration in section designing and bending beams; because ductility leads to avoid of sudden breakdown of concrete members, tolerance of change in plastic placements daring earthquake, and also reduction of inertial forces into structure. It has been assisted of concrete enclosures with the use of close taps and clamps to increase of HSC concrete bending sections ductility with its resistance increases and to reduce the effect of reducing ductility.
