[Extract] Seismic behavior of a structure is highly influenced by the response of foundation and ground. Hence, the modern seismic design codes recommend that the response analysis should be conducted by taking into consideration the whole structural system including the soil-structural interaction. 3D FEM analysis is appealing for soil-structure interaction problems as it can model soil continua and it takes into account the damping and inertial effect of soil. However, for a structure with a large number of piles, it is computationally difficult to carry out full 3D FEM analysis using solid elements for both structure and piles. This paper, investigates the use of 3-node fiber based beam elements for modeling of pile using full-scale lateral loading test on single pile and 3D FEM analysis of single pile and full-scaled bridge pier system. The finite element analysis carried out on the single pile and full-scale bridge pier exhibited that 3-node beam element can adequately simulate the behavior of concrete piles and the whole bridge systems very similar to that of full 3D analysis where piles are modeled by 20-node solid elements.
