SIMPLIFIED DESIGN METHODS OF LATERALLY LOADED PILED RAFT FOUNDATIONS

To predict behavior of laterally loaded piled raft foundations on homogenous soil, two simplified design methods are proposed. One is the corn model method and the other is the theoretical equation method. The proposed methods give the average stress distribution of piles under a piled raft foundation. Although in the condition that pile pitch is narrow, the proposed methods tend to underestimate displacement of the raft, they give fairly good agreements with the hybrid analysis results of laterally loaded piled raft foundation behaviors.
