Lateral Load Analysis of Piled Raft Foundation: A Review

Abstract

Piled raft foundation (PRF) has become the most popular system to be used in high rise buildings and other structures where a high vertical and lateral load capacity is required. The response of PRF to horizontal and vertical load is different, and factors such as pile length, diameter, spacing, raft thickness, and the presence of vertical load can affect its lateral behaviour. This article reviews recent researches from the past two decades that focuses on these factors. The primary objective is to provide a summary of recent research, highlight both experimental and numerical methods conducted for lateral load analysis of PRF. The focus is to identify the key factors influencing the lateral response of this foundation system, with particular emphasis on pile arrangement, raft stiffness, soil-structure interaction, and loading characteristics.
