Probabilistic Study of the Undrained Bearing Capacity of Strip Footings

Abstract

The undrained bearing capacity of strip footings has been extensively studied in the literature by a deterministic manner where the soil is assumed uniform. In practice, the spatial variability of random soil affects the ultimate bearing capacity of strip footings. This paper focuses on a probabilistic study using adaptive finite element limit analysis combined with random field theory to investigate the bearing capacity of strip footings subjected to vertical and centric inclined loads, on a cohesive soil with spatially variable distribution of the undrained shear strength. A parametric study is performed using OptumG2 to investigate the effects of diverse probabilistic parameters associated in the problem of undrained bearing capacity of strip footings.
