The objective is to investigate three approaches for setting up nonlinear single degree of freedom systems drawn from modal pushover curves. These curves are obtained using a non-adaptive load pattern equal to the consistent mass matrix times the modal shape. These approaches are applied on the 14-storey Grenoble City Hall studied in the framework of the ARVISE French research program. The results obtained from the Modified-UMRHA using different proposed nonlinear single degree of freedom systems are compared with those from a rigorous nonlinear response history analysis.
