It proposes the replacement of roof displacement that is used in classic “base shear – roof displacement” pushover curve with an equivalent energy-based displacement uen, calculated as a function of the work of external lateral forces acting on the structure. Consistent analytical formulas are provided for the calculation of work of lateral forces acting on the floors of an N-storey frame with rigid floor diaphragms and of the equivalent energy-based displacement. The proposed methodology is applied on characteristic multi-storey concrete frames (moment frame, wall-frame system, coupled shear walls) which are analyzed using Pushover Analysis. Results indicated that classic “base shear – roof displacement” pushover curve could lead to incorrect estimation of the amount of seismic energy the structure is able to dissipate, whereas the proposed energy-based displacement leads to an energy consistent equivalent Single Degree of Freedom (ESDOF) system.
