In this study load bearing and sharing behavior of piled raft foundations are investigated by performing laboratory model tests. Model aluminum piles with outer\inner diameters of 22\18 mm and a length of 200 mm were used. The raft was made of steel plate with plan dimensions of 176 mm x 176 mm and a thickness of 10 mm. The model piles were instrumented with strain gages to monitor pile loads in a tank 410 mm in diameter. Model piled raft configurations with 2, 4, 7, 9 piles were tested. The behavior of a single pile and the plain raft were also investigated. Tests were repeated in each group. It is observed that when a piled raft is loaded gradually piles take more load initially. Load is transferred from piles to the raft with the increasing settlements. The proportion of load that is carried by the raft decreases with the increasing number of piles, and the load per pile is decreased. The decrease is more at smaller settlements and has a limiting value for increased number of piles. Piles under the raft may carry more loads compared to single piles due to load transfer and confinement. Center, edge and corner piles are not loaded equally under rafts. It is found that rafts share foundation loads at such levels that should not be ignored.
