This paper presents a simplified method to calculate pushover curves for an asymmetric structure with displacement-dependent passive energy dissipation devices (DDPEDDs). The deformations of a symmetric structure are analyzed in translation and torsion, respectively. These results are then combined in order to calculate the pushover curve for an asymmetric structure with DDPEDDs. The numerical results obtained by using the simplified analytical method are then compared to those obtained from the analysis of the models using the software SAP2000. The results show that the simplified analytical method can be an effective tool for engineering analysis of an asymmetric structure.
