Abstract
During the past ten years, statnamic load tests have drawn attention from the piling community as one of the most economical methods for pile load tests. In this study, a small scale statnamic loading device was applied on model piled raft foundations in sand. On piled raft foundations, applicability of the unloading point method (UPM) which interprets the result of statnamic loading test was confirmed. Under statnamic loading, efficiency of pile group and load distribution ratio between the raft and the piles was investigated. As a result, the interpretation by the UPM gave acceptable results for piled raft foundations and it is possible to estimate the load distribution ratio from statnamic loading test on piled raft foundations.
