| Abstract | Analyses of independent piles tests are conducted using nonlinear finite element approach with DSC constitutive model to assess the capability of the models to predict the dynamic soil-structure interaction behavior. Instrumented axially loaded pile test at Sabine, Texas (Earth Technology Corporation, 1986) and full-scale laterally loaded pile test at Seal Beach, California (Ertec Western Inc. in Full-scale pile vibration tests, 1981) are analyzed using the finite element program DSC-DYN2D. A modified constitutive model is developed and used, and is based on the unified disturbed state concept (DSC) (Desai in Mechanics of materials and interfaces: the disturbed state concept, CRC Press, Boca Raton, 2001); both soils and interfaces are modeled using the DSC, and the parameters are determined from laboratory triaxial tests on soils and special shear tests on interfaces. Field tests results are compared with those from finite element analyses for both without and with interface behavior cases. Based on the results of this research, it can be stated that the finite element-DSC model simulation allows realistic prediction of complex dynamic soil–pile interaction problems, and is capable of characterizing behavior of saturated soils and interfaces involving liquefaction. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
