| Abstract: | In this paper, the elasto plastic seismic behavior of gravity reinforced concrete bridge piers are investigated with Takeda degrading trilinear model by using a simplified single pier model. The moment reduction factors and displacement amplification factors are defined, and the relationships between these factors and the varieties of pier height and earthquake intensities are discussed. It is important and necessary to study seismic ductility design for reinforced concrete bridge piers. |
