| Abstract | The convenience of satisfying a ductility condition at critical sections of reinforced concrete frames and continuos beams in order to avoid local failures under low loading leveis is discussed in this paper. The behaviour of rectangular reinforced concrete sections subjected to bending and axial load in ultimate limit state is studied, and direct analytical relationships between the relative depth of neutral axis x/d and the difference of tension and compression reinforcement mechanical ratios are obtained. Finally a method for the design of the reinforcement necessary to resist a bending moment with a given ductility level, in terms of x/d or w-w' is presented. The method is applied to practical cases and its interest is shown since much more ductile structures are designed without increase in the cost and in the construction difficulties. |
