Using concrete and reinforcing steel properties and axial forces, the moment capacity is obtained by equilibrium of the section. The curvature ductility and the displacement corresponding to the first yield of the extreme bar in tension and ultimate deformation of the concrete are calculated from the strain profile of the section. The design spectrum in ADSR format is used to determine the ductility demand and it is compared with the capacity of the structure. Thus, it is possible to define whether is necessary to change the initial reinforcement proposed until structural capacity is equal or bigger than the seismic demand. When this iterative procedure concludes, the section is satisfactorily designed because the analyses, as well as the design, are made simultaneously. Finally, the maximum displacement and curvature ductility are calculated. The method has been applied to a 15-storey cantilever structural wall building. The results indicate that the procedure is able to satisfy the design objectives and fulfill a non-linear deformation pattern.
