STRUCTURE--FOUNDATION INTERACTION ANALYSIS

An analysis was developed which considered the structure, continuous foundation and supporting soil as a single compatible unit. The influence of the choice of model for the soil (Winkler or linear elastic) on the moments induced in the foundation was studied for a typical three bay frame and for a range of soil and foundation stiffness. It was evident that the conventional method of analysis and the soil-line method overestimated the negative moments in the foundation but underestimated the positive moments. The bending moment diagrams were similar for both soil models for the three bay frame but for four or more bays the bending moment diagrams are vastly different. The maximum bending moment for the two models are opposite in sign.
