A new study on the behavior of pile groups using settlement based design approach ozan alver1, g rkan zden2 1: civil engineering department, bursa technical university. A pseudo-static analysis for the evaluation of the lateral behavior of pile groups francesco castelli 1 model for the analysis of the behavior of a single pile or a pile group subjected to static loadings. The static analysis of piles(pilegp) the pile cap is assumed to be rigid with the remainder of the system demonstrating elastic behavior pilegp will analyze up to 200 randomly placed piles the method allows for the determination of a pile group itself being unstable. Interaction of pile-soil-pile in battered pile groups under dynamic axial load h ghasemzadeh despite the significant progress in understanding dynamic pile group behavior homogeneous and isotropic and the pile behavior is linear elastic. Grouped and single pile behavior differs owing to the impacts of the pile-to-pile interaction ultimate lateral resistance and lateral subgrade modulus within a pile group are known as the key parameters in the soil-pile interaction phenomenon in this study, a series of experimental.
This report is a revision of a waterways experiment station technical report it describes a computerized method for pile group design and analysis as practiced in the corps of engineers and proposes criteria for systematizing this method in a new computer program example problems are included. The dynamic behavior of systems of piles and coupled pile-structure systems for assessing pile group stiffness numerical model to simulate static and dynamic lateral loading of pile groups, including. The simcenter pile-group tool provides a dynamic interface to study the behavior of a pile or pile-group in layered soil it allows the user to interactively (and nearly instantly) observe the system's response to changes of the following parameters. Static and dynamic lateral load behavior of pile groups based on full-scale testing kyle m rollins & steven r johnson civil & environmentalengineering, brigham young university. Behaviour of pile groups subjected to torsion home hkust institutional repository hkust scholarly publications scholar the pile group test results reveal that effects of lateral movement of the pile on lateral and torsional behaviours of adjacent piles exist in torsionally loaded.
It may be mentioned here that a pile group with the pile cap resting on the surface takes more load than one with free standing piles above the surface. 2 background 21 embedded pile model the embedded pile model considers the pile as slender beam elements, which is connected to the soil by embedded skin interfaces and embedded foot interfaces. Aspects of pile group and pile cap behavior under lateral loads the program of work performed in this study includes developing a full-scale field test facility, conducting approximately 30 lateral load tests on pile groups and pile caps, performing laboratory. Full-text (pdf) | embedded pile model - consisting of slender beams, skin and foot interfaces - has been successfully implemented in the plaxis 3d foundation program the interfaces represent the interaction at the contact surface between the pile and soil rigid/flexible connection and slippage.

For analyzing the behavior of pile in a group is similar to the approach used for analysis of a single pile, except that the p- large pile group design optimization with lateral resistance of pile cap. Full-scale pile group lateral load testing in soft clay by k rollins, k peterson and t weaver to improve our understanding of pile group behavior, a series of full-scale lateral load tests has been carried out on a 9-pile group. The key elements of pile group behavior, such as dependence of pile group stiffness on spacing between piles, their rigidity and length, and the distribution of loads on the raft still lacking, however, were results.
