Empirical nonlinear analysis of piled raft
Most conventional piled raft design methods focus on ultimate limit state and/or serviceability limit state, with economics being evaluated afterward. Economics is a basic requirement of the piled raft foundation design. The piled raft foundation cost estimation consists of two tasks: the material quantities and the construction labor, and its assembly include three tasks: installation, reinforcement and concrete. In this paper, piled raft construction cost is the objective function and the piled raft design parameters such as: allowable settlement, allowable differential settlement and maximum moment of the raft, are the performance indices. The design procedure in this study was obtained through two stages. At the first stage, different pile configurations were considered and the pile length, diameter and the space were changed for obtaining equal construction cost in all pile configurations. At the second stage, performance indices for each pile configuration were calculated. Each pile configuration has a maximum performance index, which is the optimum pile configuration. Sensitivity of the studies on the pile raft cost shows that, for typical pile raft foundation design, pile spacing and configuration are the key parameters in economic design. In general, it is recommended that, according to a given applied load (amount of load and load type), the optimum pile configuration method should be used in combination with a reasonable increasing of the pile length and/or pile positions to achieve the best possible behavior of the piled raft foundation.
