Identification of Sudden Stiffness Change in the Acceleration Response of a Nonlinear Hysteretic Structure
Figure 5
Acceleration responses of the simulated structure under different earthquake waves, a1 is the acceleration responses of the first floor; a2 is the acceleration responses of the second floor; aq is corresponding earthquake excitation. (a) El-Centro earthquake waves. (b) Kobe earthquake waves. (c) Northridge earthquake waves.
