This book was released on 2021-08-30 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents computational tools and design principles for piles used in a wide range of applications and for different loading conditions. The chapters provide a mixture of basic engineering solutions and latest research findings in a balanced manner. The chapters are written by world-renowned experts in the field. The materials are presented in a unified manner based on both simplified and rigorous numerical methods. The first four chapters present the basic elements and steps in analysis of piles under static and cyclic loading together with clear references to the appropriate design regulations in Eurocode 7 when relevant. The analysis techniques cover conventional code-based methods, solutions based on pile-soil interaction springs, and advanced 3D finite element methods. The applications range from conventional piles to large circular steel piles used as anchors or monopiles in offshore applications. Chapters 5 to 10 are devoted to dynamic and earthquake analyses and design. These chapters cover a range of solutions from dynamic pile-soil springs to elasto-dynamic solutions of large pile groups. Both linear and nonlinear soil behaviours are considered along with response due to dynamic loads and earthquake shaking including possible liquefaction. The book is unique in its unified treatment of the solutions used for static and dynamic analysis of piles with practical examples of application. The book is considered a valuable tool for practicing engineers, graduate students and researchers.

This book was released on 2013 with total page 774 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pile foundations that support offshore structures are required to resist not only static loading, but also dynamic loading from waves, wind and earthquakes. The purpose of this study is to gain a better understanding of the behavior of offshore piles under cyclic or dynamic loading using the finite element approach. To achieve this goal, an appropriate constitutive model is required to simulate the behavior of soils and interfaces. The DSC constitutive model is developed for saturated interfaces to study the behavior under severe shear deformation at the soil-pile interface. Monotonic and cyclic simple shear experiments are conducted on Ottawa sand-steel interfaces under drained and undrained conditions using the Cyclic-Multi-Degree-of-Freedom shear device with porewater pressure measurement (CYMDOF-P). The effect of various parameters such as normal stress, surface roughness of steel, type of loading, and the amplitude and frequency of the applied displacement in two-way cyclic loading are investigated. The data from the simple shear tests on saturated interfaces are used to calculate the parameters in the DSC model. The resulting parameters are then used to verify the DSC model by back predicting tests from which parameters are determined and independent tests that are not used in parameters determination. The model predictions, in general, were found to provide a highly satisfactory correlation with the observations. In the context of DSC, the concept of critical disturbance is developed to identify initiation of liquefaction in saturated Ottawa sand-steel interfaces. This method is based on using microstructural changes in material as an indication of liquefaction identification. The finite element method, along with DSC constitutive model, is used to investigate the response of offshore piles to dynamic loading. These include cyclic loading of axially loaded instrumented pile in clay and full-scale laterally loaded pile in sand. The DSC model is used to model the nonlinear behavior of saturated soils and interfaces. A nonlinear dynamic finite element program DSC-DYN2D based on the DSC modeling approach and the theory of nonlinear porous media is used for this purpose. Results from numerical solutions are compared with field measurements. Strong agreement between numerical predictions and field measurements are an indication of the ability to solve challenging soil-structure interaction problems. Based on the results of this research, it can be stated that the finite element-DSC model simulation allows realistic prediction of complex dynamic offshore pile-soil interaction problems, and is capable of characterizing behavior of saturated soils and interfaces involving liquefaction.

This book was released on 2012-03 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work studies the non-linear behavior of a clayey Iraqi soil taken from Baghdad city, using bounding surface plasticity model under static and dynamic loadings.There is a necessity to provide and determine the properties and the input parameters that the bounding surface plasticity model required in order to use them in non-linear soil behavior analyses under static and dynamic conditions. Site investigation is carried out and undisturbed samples are obtained.The soil test results are used in a computer program named EVAL to compute the soil properties and input parameters that are required in the bounding surface plasticity model. After input parameters became available, one could use them in finite element computer programs for static and dynamic analyses. Two-finite element programs are chosen. One for static analysis and the other for the dynamic one. The first program, named ACED used for solving coupled problems under static loading. While second program, named DLEARN, is used for solving a one-dimensional problem under sinusoidal loading and a two-dimensional problem of San Fernando dam under an earthquake load.

Download or read book Lateral Response of Piles in Saturated Cohesionless Soils written by Peter James Algie and published by . This book was released on 2012 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the lateral response of single piles embedded in saturated cohesionless soils on flat ground, with no crust layer. OpenSeesPL, a numerical modelling software programme, was used as the principal means of this investigation. Several 'rules of thumb' that could be used in pseudo-static methods were developed. Soil-pile interaction in saturated cohesionless soils is a changing and multi-variable problem, and therefore is not well understood. This is because the soil is prone to liquefaction when subject to dynamic loads. These variables include changing soil stiffness and damping, changing soil-pile-structure resonant frequency and changing loads. The response of piles subject to lateral static pushover loads was considered. OpenSeesPL and an elastic continuum pile analysis method proposed by Budhu and Davies (1987) can predict lateral pile response reasonably accurately. Initial soil stiffness equal to approximately 1/3 to 1/4 of the small strain moduli should be used. The friction angle in both analysis methods has to account for strain softening beyond peak resistance in dense sands. Pile response subject to lateral dynamic loads at the pile head was analysed. It was found that piles dynamically loaded at the pile head can lead to the adjacent soil liquefying, which reduces the soil stiffness and increases the strain dependent material damping. Nonlinear OpenSeesPL models and an inertial pseudo-static method along with the Budhu and Davies method for elastic soils with appropriate reductions in soil stiffness can be used to reasonably predict the response of piles dynamically excited at the pile head. The lateral response of piles subject to dynamic excitation of the underlying bedrock was investigated. Maximum ground surface accelerations and pile response in liquefiable soils was found to occur during an initial transient phase before the onset of full liquefaction. During this phase, the soil has a linear stiffness distribution with depth and the soil stiffness near the ground surface (i.e. at one pile diameter) is equal to approximately 20% of the initial stiffness at that depth. An elastic equivalent pseudo- static method for determining lateral pile response subject to kinematic and inertial interaction was developed.

Download or read book A Non linear Dynamic Macroelement for Soil Structure Interaction Analyses of Piles in Liquefiable Sites written by Varun and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A macroelement is developed for soil-structure interaction analyses of piles in liquefiable soils, which captures efficiently the fundamental mechanisms of saturated granular soil behavior. The mechanical model comprises a nonlinear Winkler-type model that accounts for soil resistance acting along the circumference of the pile, and a coupled viscous damper that simulates changes in radiation damping with increasing material non-linearity. Three-dimensional (3D) finite element (FE) simulations are conducted for a pile in radially homogeneous soil to identify the critical parameters governing the response. The identified parameters, i.e., hydraulic conductivity, loading rate of dynamic loading, dilation angle and liquefaction potential are then expressed in dimensionless form. Next, the macroelement parameters are calibrated as a function of the soil properties and the effective stress. A semi-empirical approach that accounts for the effects of soil-structure interaction on pore pressure generation in the vicinity of pile is used to detect the onset of liquefaction. The predictions are compared with field data obtained using blast induced liquefaction and centrifuge tests and found to be in good agreement.
