The presentation will discuss nonlinear structural analysis of existing buildings. Existing reinforced concrete frame structure behavior will be analyzed through three typical pushover procedure steps, completely implemented in midas Gen:
(i) nonlinear static analysis, (ii) estimation of seismic demand through definition of single degree of freedom equivalent system, (iii) calculation of capacity and safety verification. Reference code is EN 1998-
3:2005, “Eurocode 8: Design of structures for earthquake resistance - Part 3: Assessment and retrofitting of buildings”.
