Reliability-Based Analysis and Design of Eccentrically Loaded Footings
This paper presents a reliability-based approach for the analysis and design of a shallow strip footing subjected to an eccentric load. Only the punching failure mode of the ultimate limit state is considered in this paper. The deterministic model used is based on two rotational double-spiral failure mechanisms in limit analysis. The random variables used are the soil shear strength parameters. The hypothesis of uncorrelated shear strength parameters was found conservative in comparison to the one of negatively correlated variables. The coefficient of variation of only the angle of internal friction has a significant effect on the failure probability. For design, an iterative procedure is performed to determine the breadth of the footing for a target failure probability.
