Abstract
Dynamic response of a segmental (modular block) retaining wall system to recorded ground motions is investigated. The magnitude and characteristics of wall response are compared to those obtained under harmonic input base acceleration. The calculated maximum lateral displacement and reinforcement load of the segmental retaining wall mode1 subjected to a single frequency, harmonic input acceleration were considerably larger than the corresponding values obtained using a number of earthquake accelerograms with comparable predominant frequencies. It is concluded that the random characteristic of actual ground acceleration may partly explain the relatively good performance of reinforced-soil retaining wall systems that were designed without seismic considerations or at best using simple pseudo-static limit equilibrium methods. Nevertheless, it was found that low-frequency ground motions with high intensity values can result in significant structural response magnitude of short-period retaining wall systems.
