Book Description
The objective of this research is to develop resistance factors for use in the load and resistance factor design (LRFD) method for consolidation settlements of shallow foundations and embankments on cohesive soil. Probabilistic analysis of settlements is used to represent the uncertainty of the compression index, Cc, the recompression index, Cr and the uncertainty of the maximum past pressure, P'c. The probabilistic analysis is based on the Monte Carlo simulation for five different probabilities of failure: 1/25, 1/50, 1/75, 1/100, 1/150 for foundation soils and 1/150, 1/2000 for embankment fill.

Book Description
Considered the standard engineering reference on shallow foundations, this edition strengthens that position. Completely reworked and written by one of the top men in the field, it covers all the latest developments and approaches. Equally valuable to researchers and designers as it is to engineering students, this resource updates data and provides revised theories on the ultimate and allowable bearing capacities of shallow foundations. It adds refinements to a number of unique circumstances such as foundations on soil with geogrid reinforcement as well as bearing capacity relationships for shallow foundations subjected to eccentric and inclined loads. It also covers advances in reinforcement materials.

Book Description
Probabilistic analyses were performed to study the effect of the number of measurements on the reliability of spread footings designed using load and resistance factor design (LRFD). Several alternative methods, including a new proposed method, to practically account for the uncertainty in soil design parameters were evaluated for designs using small numbers of measurements. Results show that design parameters are largely affected by the number of measurements, thus, in turn, the reliability of foundation designs highly depends on the number of measurements. Use of the penalty function and the one-sided upper confidence bound method effectively reduces the percentage of “unconservative” cases when the number of measurements is small.

Book Description
Shallow Foundations: Discussions and Problem Solving is written for civil engineers and all civil engineering students taking courses in soil mechanics and geotechnical engineering. It covers the analysis, design and application of shallow foundations, with a primary focus on the interface between the structural elements and underlying soil. Topics such as site investigation, foundation contact pressure and settlement, vertical stresses in soils due to foundation loads, settlements, and bearing capacity are all fully covered, and a chapter is devoted to the structural design of different types of shallow foundations. It provides essential data for the design of shallow foundations under normal circumstances, considering both the American (ACI) and the European (EN) Standard Building Code Requirements, with each chapter being a concise discussion of critical and practical aspects. Applications are highlighted through solving a relatively large number of realistic problems. A total of 180 problems, all with full solutions, consolidate understanding of the fundamental principles and illustrate the design and application of shallow foundations.

Book Description
The biggest problem for a shallow foundation, just as for any other type of foundation, is a failure due to an overestimation of the bearing capacity. This means that the correct prediction of the bearing capacity of the foundation is often the most important part of the design of a civil structure. That is why the publication by Prandtl in 1920 about the hardness of a plastic body, was a major step in solving the bearing capacity of shallow foundations, although it is well possible that he never realised this, because his solution was not made for civil engineering purposes, but for mechanical purposes. Over the last 100 years, a lot of extensions have been made, for example with inclination factors and shape factors. Also many laboratory experiments have been done and numerical calculations have been made. Some even try to extrapolate the failure mechanism for shallow foundations to the failure mechanism around the tip of a pile. All this scientific work leads back to the first publication by Ludwig Prandtl in 1920. This book, “100 Years of Prandtl’s Wedge”, is intended for all those who are interested in these fundamentals of foundation engineering and their history. The Appendices include a copy of Prandtl’s Über die Härte plastischer Körper and of Reissner’s publication of 1924, Zum Erddruckproblem.
