Nonlinear analytical modeling of dam gated pier based on earthquake records

Abstract

In the seismic evaluation of dam gated piers, which are a part of dams, it is necessary to construct an analytical model that is separate from the dam body. For that purpose, it is important to grasp the relationship between behaviors of the dam body and the dam gated pier. In this study, push-over analysis using a solid model realized that the behavior of the dam body and the characteristic shape of the dam crest affect the behavior of the dam gated pier. In addition, by reproduction analysis using seismic observation results, it was shown that when using the M-φ model to simplify the analysis model, the effect can be considered by installing a spring element at the foundation.
