Curvature Ductility Factor of Rectangular Sections Reinforced Concrete Beams
Abstract:The present work presents a method of calculating the ductility of rectangular sections of beams considering nonlinear behavior of concrete and steel. This calculation procedure allows us to trace the curvature of the section according to the bending moment, and consequently deduce ductility. It also allowed us to study the various parameters that affect the value of the ductility. A comparison of the effect of maximum rates of tension steel, adopted by the codes, ACI , EC8  and RPA  on the value of the ductility was made. It was concluded that the maximum rate of steels permitted by the ACI  codes and RPA  are almost similar in their effect on the ductility and too high. Therefore, the ductility mobilized in case of an earthquake is low, the inverse of code EC8 . Recommendations have been made in this direction.
