Two-way cyclic lateral loading tests are performed at alluvial soft deposits to evaluate the behavior of piled raft foundations, which have rigid joint or pin joint at pile heads. Each foundation consists of a 2.0m wide by 1.5m long concrete block with 20 kN/m^2 loadings, and two steel pipe piles (pile spacing to diameter ratio = 10) arranged in a line. The displacement and stress of these foundations are compared to those of a single pile tested at the same site. The results show that the piled raft with the pin joint at pile head is specifically effective foundation.
