Behavioral analysis of the disconnected piled raft foundation (DPRF) is more complicated than the conventional piled raft foundation owing to the complex interactions between piles, subsoil, and load transfer platform (LTP). The effect of pile-related parameters and LTP-related parameters on load-settlement behavior of DPRF has been compared by 3-dimentional numerical work. The result of this study shows that both pile-related factors and LTP-related factors affect the load-settlement of DPRF. The simple equation to estimate the load-settlement behavior of DPRF system has been suggested in terms of pile contribution factors. The results of previous studies were also analyzed to verify the validity of suggested equation. A good agreement between the measured and estimated values were obtained, indicating the potential to apply in practical field.
