Model Uncertainties in Foundation Design


Book Description

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.




Proceedings of the 4th International Conference on Performance Based Design in Earthquake Geotechnical Engineering (Beijing 2022)


Book Description

The 4th International Conference on Performance-based Design in Earthquake Geotechnical Engineering (PBD-IV) is held in Beijing, China. The PBD-IV Conference is organized under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering - Technical Committee TC203 on Earthquake Geotechnical Engineering and Associated Problems (ISSMGE-TC203). The PBD-I, PBD-II, and PBD-III events in Japan (2009), Italy (2012), and Canada (2017) respectively, were highly successful events for the international earthquake geotechnical engineering community. The PBD events have been excellent companions to the International Conference on Earthquake Geotechnical Engineering (ICEGE) series that TC203 has held in Japan (1995), Portugal (1999), USA (2004), Greece (2007), Chile (2011), New Zealand (2015), and Italy (2019). The goal of PBD-IV is to provide an open forum for delegates to interact with their international colleagues and advance performance-based design research and practices for earthquake geotechnical engineering.




The Application of Stress-wave Theory to Piles


Book Description

"This volume contains 101 papers presented at the 8th International Conference on the Application of Stress Wave Theory to Piles, held in Lisbon, Portugal in 2008." "It is divided in 14 chapters according to the conference themes: Wave mechanics applied to pile engineering; Relationship between static resistance to driving and long-term static soil resistance; Case histories involving measurementand analysis of stress waves; Dynamic monitoring of driven piles; Dynamic soil-pile interaction models - numerical and physical modeling; High-strain dynamic test; Low-strain dynamic test; Rapid-load test; Monitoring and analysis of vibratory driven piles; Correlation of dynamic and static load tests; Quality assurance of deep foundations using dynamic methods; Incorporation of dynamic testing into design codes and testing standards; Ground vibrations induced by pile motions; Dynamic measurements in ground field testing." "This conference aims to contribute to a better and more efficient professional interaction between specialized contractors, designers and academicians. By joining the contribution of all of them it was possible to elucidate the today's state-of-the-art in science, technology and practice in the application of stress wave theory to piles."--BOOK JACKET.







Full-Scale Field Tests of Different Types of Piles


Book Description

This book provides full-scale field tests of different types of pile foundations. For the testing, it includes static load tests which consider various loading orientations, dynamic load tests, inclinometer monitoring and tests that aim to determine the load transfer mechanism of pile foundation. This book also covers the up-to-date popular topic with detailed project studies. This includes the academic investigation of post-grouting technology effect on drilled shaft piles, the research of displacement and non-displacement precast pile foundation, the study of fiber-reinforced polymer material used in the geo-technical environment such as deep excavation pit in tunneling project, and the research of super-long and large diameter pile foundations. These investigations provide essential and academic information for researchers as well as engineers in role of Civil and Geotech. Not only the different types of the piles are studied, but also the relevant theory and literatures are reviewed. In this book, the diagrams are plotted in an easy way and the explanation of the diagrams and tables are described in detail. The research methods corresponding to the practical projects are detailed as well. Hence, it is useful as a reference for the students and researchers in civil and geotechnical engineering.
