This report focuses on the development of a new method of analysis of laterally loaded piles embedded in a multi-layered soil deposit treated as a three-dimensional continuum. Assuming that soil behaves as a linear elastic material, the governing differential equations for the deflection of laterally loaded piles were obtained using energy principles and calculus of variations. The differential equations were solved using both the method of initial parameters and numerical techniques. Soil resistance, pile deflection, slope of the deflected pile, bending moment and shear force can be easily obtained at any depth along the entire pile length. The results of the analysis were in very good agreement with three-dimensional finite element analysis results. The analysis was further extended to account for soil nonlinearity. A few simple constitutive relationships that allow for modulus degradation with increasing strain were incorporated into the analysis. The interaction of piles in groups was also studied.

Maintenance, Safety, Risk, Management and Life-Cycle Performance of Bridges contains lectures and papers presented at the Ninth International Conference on Bridge Maintenance, Safety and Management (IABMAS 2018), held in Melbourne, Australia, 9-13 July 2018. This volume consists of a book of extended abstracts and a USB card containing the full papers of 393 contributions presented at IABMAS 2018, including the T.Y. Lin Lecture, 10 Keynote Lectures, and 382 technical papers from 40 countries. The contributions presented at IABMAS 2018 deal with the state of the art as well as emerging concepts and innovative applications related to the main aspects of bridge maintenance, safety, risk, management and life-cycle performance. Major topics include: new design methods, bridge codes, heavy vehicle and load models, bridge management systems, prediction of future traffic models, service life prediction, residual service life, sustainability and life-cycle assessments, maintenance strategies, bridge diagnostics, health monitoring, non-destructive testing, field testing, safety and serviceability, assessment and evaluation, damage identification, deterioration modelling, repair and retrofitting strategies, bridge reliability, fatigue and corrosion, extreme loads, advanced experimental simulations, and advanced computer simulations, among others. This volume provides both an up-to-date overview of the field of bridge engineering and significant contributions to the process of more rational decision-making on bridge maintenance, safety, risk, management and life-cycle performance of bridges for the purpose of enhancing the welfare of society. The Editors hope that these Proceedings will serve as a valuable reference to all concerned with bridge structure and infrastructure systems, including students, researchers and engineers from all areas of bridge engineering.

This report presents the details of the first integral abutment bridge in the state of Iowa that utilized precast, prestressed concrete piles in the abutment. The bridge, which was constructed in Tama County in 2000, consists of a 110 ft. long, 30 ft. wide, single-span PC girder superstructure with a left-side-ahead 20 degree skew angle. The bridge was instrumented with a variety of strain gages, displacement sensors, and thermocouples to monitor and help in the assessment of structural behavior. The results of this monitoring are presented, and recommendations are made for future application of precast, prestressed concrete piles in integral abutment bridges.

The complexities of designing piles for lateral loads are manifold as there are many forces that are critical to the design of big structures such as bridges, offshore and waterfront structures and retaining walls. The loads on structures should be supported either horizontally or laterally or in both directions and most structures have in common t

It is the aim of this research work is to investigate and to assess quatitatively as well as quantitatively the bearing behaviour of pile groups subjected to cyclic lateral loading. In this context, the influences of different boundary conditions, in particular the soil properties and the pile group geometry are to be analysed experimentally and numerically. Based on a brief literature review in chapter 2, model tests (centrifuge and small-scale at 1g) and numerical investigations have been carried out to contribute to a better understanding of the cyclic behaviour of pile groups. Chapter 3 describes the test procedure and summarises the results of centrifuge tests, which have been carried out at the Centre for Offshore Foundation Systems (COFS) in Perth, Australia. Further investigations have been carried out by means of smallscale model tests at 1g in the testing facilities at the University of Kassel, Germany, with the results as summarised in chapter 4. A comparison of individual results of both test series is provided in chapter 5. The numerical studies in chapter 6 have been carried out in order to analyse the general ability of numerical simulations to calculate the response of pile groups to cyclic lateral loading. Based on the previously derived results, chapter 7 provides equations that can be applied to estimate the cyclic accumulation of lateral displacements of pile groups as well as the cyclic changes of the load distribution within pile groups.

This book presents models that capture the nonlinear response of piles subjected to lateral forces. Utilising a consistent approach encompassing new mathematical models, it offers solutions presented as closed-form expressions and underpinned by the same set of 3-5 measurable soil-input parameters. These focus on nonlinear response of mono piles, anchored piles, pile groups, and torsional piles, as well as passive piles subjected to soil movement induced in shearing, sliding slopes or excavation, and earthquake shaking. The models can also be used for pipelines and similar beam structures. Solutions are provided in the form of design charts, with each parameter obtained using available test data and illustrated with real-world cases. The models reveal, for the first time, the mysterious mechanisms of amplification resulting from back-rotation, which have incurred the collapse of structures such as the Showa Bridge and Nicoll Highway, as well as the distortion of piles during earthquakes. Advanced Design of Pile Foundations Under Lateral Loading is ideal for practicing foundation engineers and students at graduate level.
