Undrained bearing capacity and mechanisms of collapse of square footings under vertical and moment loads
Undrained bearing capacity and mechanisms of collapse of square footings under vertical and moment loads
Shallow foundations are typically required to carry a combination of vertical and moment loads and undrained bearing failure is a fundamental consideration. Many structures are founded on shallow foundations of low aspect ratio and idealisation to conditions of plane strain is inappropriate. Analytical studies have addressed the response of circular footings to uniaxial vertical loading and combined vertical and moment loading in the past but square and rectangular foundation geometry has been largely overlooked. This paper reports results from a suite of finite element analyses addressing the undrained bearing failure of square footings subjected to vertical and moment loading. Ultimate limit states and the kinematic mechanisms accompanying failure observed in the finite element analyses are presented in the context of other available solutions for strip, circular and square footings.

Abstract
Shallow foundations are typically required to carry a combination of vertical and moment loads and undrained bearing failure is a fundamental consideration. Many structures are founded on shallow foundations of low aspect ratio and idealisation to conditions of plane strain is inappropriate. Analytical studies have addressed the response of circular footings to uniaxial vertical loading and combined vertical and moment loading in the past but square and rectangular foundation geometry has been largely overlooked. This paper reports results from a suite of finite element analyses addressing the undrained bearing failure of square footings subjected to vertical and moment loading. Ultimate limit states and the kinematic mechanisms accompanying failure observed in the finite element analyses are presented in the context of other available solutions for strip, circular and square footings.
