Abstract

Torsional loads can be significant on shallow foundations for large onshore structures, such as wind turbines. However, torsional effects for circular foundations under a zero-tension interface condition have not been well studied. This paper shows the results of finite element analysis of circular foundations with a no-tension interface under combined vertical, horizontal, moment and torsional loading. Similar equations to current forms of V-H expression are applied to model the V-T relationship. The normalized H-T and M-T envelopes have been simulated with existing analytical equations, but with some modifications. The developed approaches will provide improved design methods for estimating torsional capacity of shallow foundations.
