Full Description
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.
