1 Bridges are often constructed with a single enlarged shaft foundation supporting a column. In many cases, the shaft foundation is constructed with a permanent steel casing.

2 Contribution of Steel Casing to Single Shaft Foundation Structural resistance Developing the strength of the steel casing in drilled shafts implies that the shaft will add strength, whether it behaves as a composite or non-composite RCFST. In most cases, the strength of the non-composite RCFST is on the order of 10–20% less than that of the composite case.

Summary 3 However, the behavior of the reinforced concrete core becomes more dominant as the D/t ratio increases. • A change in the D/t ratio does not change the friction coefficient that is needed to develop full composite action.

4 Contribution of Steel Casing to Single Shaft Foundation Structural resistance • Based on the experimental results and supporting finite element analyses results, new ultimate and damage-controlling limit states were proposed for displacement-based design purposes. • The existing effective stiffness equations in various codes and design guidelines were evaluated by comparing the equations with the experimental and finite element results.
