"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.

Resistance factors were developed in the framework of reliability theory for the Load and Resistance Factor Design (LRFD) of driven pile's axial capacity in North Carolina utilizing pile load test data available from the North Carolina Department of Transportation. A total of 140 Pile Driving Analyzer (PDA) data and 35 static load test data were compiled and grouped into different design categories based on four pile types and two geologic regions. Resistance statistics were evaluated for each design category in terms of bias factors. Bayesian updating was employed to improve the statistics of the resistance bias factors, which were derived from a limited number of pile load test data. Load statistics presented in the current AASHTO LRFD Bridge Design Specifications were used in the reliability analysis and the calibration of the resistance factors. Reliability analysis of the current NCDOT practice of pile foundation design was performed to evaluate the level of safety and to select the target reliability indices. Resistance factor calibration was performed for the three methods of static pile capacity analysis commonly used in the NCDOT: the Vesic, the Nordlund, and the Meyerhof methods. Two types of First Order Reliability Methods (Mean Value First Order Second Moment method and Advanced First Order Second Moment method) were employed for the reliability analysis and the calibration of the resistance factors. Recommended resistance factors are presented for the three methods of static pile capacity analysis and for seven different design categories of pile types and geologic regions. The resistance factors developed and recommended from this research are specific for the pile foundation design by the three static capacity analysis methods and for the distinct soil type of the geologic regions of North Carolina. The methodology of the resistance factor calibration developed from this research can be applied to the resistance factor calibration for other foundation.

Driven piles have been frequently used by highway engineers to support bridges, retaining walls, and overhead signs. Prior to pile driving, engineers need to estimate the required pile length based on soil information and soil mechanics principles. During pile driving, engineers need to verify the load-carrying capacity and integrity of each driven pile. The analysis tools for pile length estimation and dynamic pile testing techniques for pile-driving control constitute the two main focuses of this research.

"The Missouri Department of Transportation (MoDOT) has recently migrated from allowable stress design (ASD) to load and resistance factor design (LRFD) of driven piles. This transition was initiated when the Federal Highway Administration (FHWA) issued a policy stating that all new bridge designs shall be designed in accordance with the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge Design Specifications to eliminate the difference in design methodologies for bridge superstructures and bridge substructures. However, the resistance factors for driven piles specified in the AASHTO LRFD specifications are based on nationwide pile data, consisting of a wide range of different geologies, subsurface conditions, and installation procedures. For MoDOT to fully benefit from the transition from ASD to LRFD, resistance factors based on MoDOT's local practices and geologic conditions must be developed. The presented research was dedicated to collecting pile load test data to allow the calibration of resistance factors for ultimate limit state design for predictive methods used by MoDOT to determine pile capacity, as well as to develop related reliability-based quality control criteria of driven pile foundations. MoDOT's current state of practice was evaluated and all available pile load test data was collected. However, MoDOT has records for only 10 pile load tests. Therefore, the search was extended to Missouri's eight neighboring states by distributing questionnaires to surrounding state transportation administrations in hope of gathering pile data. Surrounding states have different geologic conditions, but any collected pile data could be matched to similar soil and rock formations in Missouri's geologic regions. Only five out of eight states responded to the questionnaire, and there was no pile load test data obtained from the states that responded. Therefore, the calibration of resistance factors could not be performed based on the research approaches. The deformation behavior of MoDOT bridge pile foundations was also evaluated at the serviceability limit state by modeling pile foundations in FB-MultiPier. The results indicated that pile displacement is an important factor for the development of serviceability resistance factors for pile foundations. Lastly, recommendations for future MoDOT practice and future research efforts regarding driven piles are provided"--Abstract, leaf iii.
