The '''Enduranceendurance time''' ('''ET)''') '''method''' is a [[Structural dynamics|dynamic structural analysis]] procedure for seismic assessment of structures. In this procedure, an intensifying dynamic excitation is used as the [[Structural load|loading]] function.<ref name=w2/> Endurance time method is a time-history based dynamic analysis procedure. An estimate of the structural response at different equivalent [[Seismic hazard|seismic intensity]] levels is obtained in a single response history analysis.<ref name=j2/> This method has applications in [[Seismic analysis|seismic assessment]] of various structural types and in different areas of [[earthquake engineering]].
