Abstract

The interaction between a surface foundation and the supporting inelastic soil under the action of monotonic, cyclic, and seismic loading is studied numerically. The foundation supports an elastic tall system, the horizontal loading of which induces primarily an overturning moment and secondarily a shear force. Starting from linear elastic behavior, the footing eventually uplifts from the soil, provoking strong inelastic soil response culminating in development of a bearing–capacity failure mechanism and progressive settlement. The substantial lateral displacement of the pier mass induces an additional aggravating moment due to P–δ effect. The paper outlines the moment–rotation–settlement relations under monotonic loading at the mass center, under cyclic loading, and under seismic excitation at the base.

Pushover and Inelastic-Seismic Response of Shallow Foundations Supporting a Slender Structure

San Diego, California

The interaction between a surface foundation and the supporting inelastic soil under the action of monotonic, cyclic, and seismic loading is studied numerically. The foundation supports an elastic tall system, the horizontal loading of which induces primarily an overturning moment and secondarily a shear force. Starting from linear elastic behavior, the footing eventually uplifts from the soil, provoking strong inelastic soil response culminating in development of a bearing–capacity failure mechanism and progressive settlement. The substantial lateral displacement of the pier mass induces an additional aggravating moment due to P–δ effect. The paper outlines the moment–rotation–settlement relations under monotonic loading at the mass center, under cyclic loading, and under seismic excitation at the base.
