ABSTRACT

Classical methods for analyzing shallow foundations generally do not include the effects of torsion loading, as such loading is relatively uncommon; however, analyses of a few special cases have been reported. Torsion effects on the sliding resistance of a group of surface footings were addressed by Murff and Miller (1977) using the upper bound method. More recently Finnie and Morgan (2004) used limit equilibrium methods to study torsion-sliding response of rectangular surface footings andYun et al. (2009) have used the finite element method to study the interaction among sliding, torsion and vertical load on surface footings.
