| 要旨 |
Seismic behavior of a structure is highly influenced by the response of foundation and ground. In this paper, 3D FEM analysis was carried out on single concrete piles and full-scaled bridge pier considering soil-structure interaction. Comparison between 20-node solid element and 3-node beam element was carried out for the modeling of concrete pile. Verification with full-scale lateral loading test on concrete piles and 3D FEM analysis showed that fiber based beam element can adequately simulate the lateral behavior of pile. |
