ESTIMATION OF INELASTIC LONGITUDINAL ABUTMENT STIFFNESS OF BRIDGES
A simplified method for the construction of a force-displacement diagram of a bridge abutment is presented. The method consists of the modeling of the soil as a Winkler foundation with springs that can either be constant or vary linearly with depth. The soil springs are considered to be linearly elastic but the soil deposits on the left and right sides of the abutment are allowed to yield. The yielding criterion used for the soil deposits is based on the Rankine theory of active thrust and passive resistance. The paper describes the fundamental concepts of soil mechanics and abutment design. The simplifying assumptions of the analysis are provided together with the statatement of the simplified problem and its solution.
