This paper presents an alternative loading test to verify load-carrying capacities on concrete filled tubular columns in multi-columns composite bridge piers. The elasto-plastic analysis was carried out by using the fiber model. As a result, the load-carrying capacity and fracture process of the proposed multi-columns composite pier was made clear. In addition the validity of the elasto-plastic analysis using fiber model was proved by comparison with experimental results.
