Abstract

This paper presents the results of footing load tests conducted on compacted sand beds to evaluate the bearing capacity and load-displacement characteristics of shallow foundations. Tests were conducted on square concrete footings with widths of 0.30, 0.61, 0.91, and 1.22 m and with embedment ratios (D/B) of 0, 0.5, and 1.0 to investigate the influence of footing size and embedment on the load-displacement behavior and ultimate bearing capacity. A description of the soil and test procedures used is given and the results of the footing load tests are presented. A discussion of the definition of ultimate bearing capacity and the use of normalized curves to describe the footing behavior is presented. A simple model is presented that may prove useful for the design of shallow foundations on sands.

Bearing Capacity of Footings on Compacted Sand

St. Louis, Missouri

This paper presents the results of footing load tests conducted on compacted sand beds to evaluate the bearing capacity and load-displacement characteristics of shallow foundations. Tests were conducted on square concrete footings with widths of 0.30, 0.61, 0.91, and 1.22 m and with embedment ratios (D/B) of 0, 0.5, and 1.0 to investigate the influence of footing size and embedment on the load-displacement behavior and ultimate bearing capacity. A description of the soil and test procedures used is given and the results of the footing load tests are presented. A discussion of the definition of ultimate bearing capacity and the use of normalized curves to describe the footing behavior is presented. A simple model is presented that may prove useful for the design of shallow foundations on sands.
