Model Uncertainties in Foundation Design
Model Uncertainties in Foundation Design is unique in the compilation of the largest and the most diverse load test databases to date, covering many foundation types (shallow foundations, spudcans, driven piles, drilled shafts, rock sockets and helical piles) and a wide range of ground conditions (soil to soft rock). All databases with names prefixed by NUS are available upon request. This book presents a comprehensive evaluation of the model factor mean (bias) and coefficient of variation (COV) for ultimate and serviceability limit state based on these databases. These statistics can be used directly for AASHTO LRFD calibration. Besides load test databases, performance databases for other geo-structures and their model factor statistics are provided. Based on this extensive literature survey, a practical three-tier scheme for classifying the model uncertainty of geo-structures according to the model factor mean and COV is proposed. This empirically grounded scheme can underpin the calibration of resistance factors as a function of the degree of understanding – a concept already adopted in the Canadian Highway Bridge Design Code and being considered for the new draft for Eurocode 7 Part 1 (EN 1997-1:202x). The helical pile research in Chapter 7 was recognised by the 2020 ASCE Norman Medal.
Foundation Engineering in the Face of Uncertainty
Sponsored by the Geo-Institute of ASCE. Foundation Engineering in the Face of Uncertainty, GSP 229, honors Fred H. Kulhawy, Ph.D., P.E., G.E., Dist.M.ASCE, for his many contributions advancing the science, art, teaching, and practice of geotechnical engineering. Dr. Kulhawy has influenced the civil engineering profession worldwide with his willingness to share his knowledge and expertise in many areas of geotechnical engineering including soil and rock mechanics, foundation engineering, and engineering geology. This collection contains 54 papers that explore uncertainty in foundation engineering, including characterization of soil parameters, spatial variability, uncertainty and risk analyses, reliability analysis, and reliability-based design. Seventeen papers are reprints of classic papers authored or co-authored by Dr. Kulhawy, and 37 invited technical papers are contributions by experts from around the world, which also include informative case histories. Foundation Engineering in the Face of Uncertainty contains practical and technical information on risk and reliability in foundation engineering that will be of interest to geotechnical engineers, foundation specialists, engineering geologists, and researchers.
