Recent experimental tests have identified the presence of large-amplitude high-frequency acceleration spikes in the dynamic response of rocking wall structures. The current study is focused on the investigation of the effects of these acceleration spikes on the dynamic performance of rocking wall structures. For this purpose, a 4 story rocking wall structure is designed and the response history analysis is performed. The results show a significant contribution of higher modes in the acceleration response which can increase the shear demand considerably. To further investigate these higher mode accelerations, inelastic modal decomposition of dynamic response is performed. Results show that the inelastic modal decomposition technique can be effectively used to understand and quantify the effects of these acceleration spikes and it can also be employed to check the effectiveness of different mitigation strategies for acceleration spikes.
