An Iterative Elastic-Bar Method Considering Frame Structure-Foundation Interaction

An iterative elastic-bar method for calculating the foundation internal stresses of multistorey and highrise frame structures is presented in this paper.
A calculating model is adopted which assumes that the contact relations between foundation and soil could be replaced by rigid-bars and elastic-bars could be instead of frame columns. The effects of columns' bendings tiffness, columns' axial deformation, and the lage due to structural stiffness have been taken into account. The method is in good agreement with the practical measurements.
