Spreadsheets for the analysis of piled raft foundations

Abstract

In the design of foundations in piled rafts, a great number of unknown facts are determined in order to obtain a rational foundation, which in turn meets the requirements of the project. The use of spreadsheets facilitates the work for the designer, to estimate the dimensions of foundation, thus evaluating the influence of various parameters involved in the design, so as to finally use computer programs for the final calculation. This paper shows the results obtained from spreadsheets programmed by MathCad and, it compares the values of the estimated curve load v/s deformation of spreadsheets with the results of full scale models and others from literature on the subject.
