Abstract

In this paper, a simplified calculation model for the prediction of the load-carrying capacity of an RC column footing with a square cross section is presented. A detailed background of available experimental data and existing models for the prediction of the load-carrying capacity of slender and deep footings is presented. Cases of flexural failure and punching shear failures for slender footing and concrete strut crushing and tie yielding in deep members are analyzed. The aim of the paper is to propose a simple design formula for slender and deep footing verified by available experimental data and in agreement with other existing expressions. Expressions of the maximum mechanical ratio of main steel for slender and deep footing are defined to avoid brittle failure. The effects of the main parameters, such as the dimensions of the footing and column (depth, width) and the mechanical ratio of longitudinal steel and type of soil, were investigated both numerically and analytically. A comparison between analytical and numerical results shows good agreement.
