Description APRAF, using a combination of finite layer and finite element methods to model layered soil, raft and piles, can be used to calculate the displacements, bending moments and shear forces in rafts and piles. Piled rafts can be penetrated into layered soil and subjected to general loadings. The soil is divided into horizontal layers and each layer has different elastic properties. The elastic properties can vary from layer to layer. The raft is modelled as a thin elastic plate and divided up into rectangular elements, which can be in contact with the soil or clear of the soil. The piles are modelled as elastic beams and broken up into elements joined at nodes that correspond to the soil layer interfaces. Finite layer theory is employed to analyse the layered soil while finite element theory is used to analyse the raft and piles. The program allows point loads to be applied to raft nodes in any of x, y or z directions and uniform loadings can be applied to any raft elements in any axis. Similarly, moments can be applied in x, or y-direction. Output can be limited to only some raft elements and some of piles.
