Practical Calculations of Contact Reactions for Box Foundations

On the basis of recent research and measurement results of tall building box foundations, contact reactions and its effecting factors are discussed and compared in this paper. The method of calculating contact reactions by layers summation procedure are improved and tables compiled for practical use are included. Hereby, the reactions and conventional settlements can be calculated upon the same base in considering the effective factors on reactions. Calculated results are rather in agreement with measured values.The suggested methods are also adaptable to calculate contact reactions of rectangular box foundation on layered subsoil conditions.
