Abstract

Flexible reinforced concrete pier with I-shape cross section (FRCP-I) is originally designed in Japan, and is used as the high pier of expressway in mountainous area. The FRCP-I consists of the side columns and the shear wall. Therefore, the FRCP-I is expected to absorb more earthquake energy than the other types of piers. In this study, based on the horizontal loading tests, it is found that the failure type of the FRCP-I is the flexural shear compression failure instead of the brittle shear failure. Moreover, the restoring force characteristics and the deformation capacities are clarified. Deformation capacities of this pier obtained by finite element (FE) analysis coincide with the experimental results.
