Dynamic Analysis to Study Soil-Pile Interaction EffectsAuthors: Pallavi Ravishankar,Neelima Satyam Journal: Indexed in Scopus Compendex and Geobase Elsevier, Chemical Abstract Services-USA, Geo-Ref Information Services- USA, List B of Scientific Journals, Poland, Directory of Research Journals (link) Volume: 7 Volume Number: 4 Pages: 655-658 Date: 2014-08-29 Report no: IIIT/TR/2014/92 AbstractThe prediction of the behaviour of the pile foundations is of paramount importance in the seismic design and assessment piles for the structural sustainability during earthquake. Generally pile provides a good agreeable performance in the complex soils conditions like soft soils having less bearing capacity. The nonlinear condition and dynamic condition are coupled with each other to produce the complex soil action to the pile motion which can be well captured by the soil structure interaction phenomenon stated as soil-pile interaction analysis. In this research paper numerical analysis of a single pile is carried out for a different soil conditions like, C-soils, Ø-Soils and C- Ø soils to understand the soil-pile interaction for the EL-Centro (1940) ground motion. The displacements profiles are studied for flexible long and rigid short pile for the different soil types as mentioned earlier and soil pile interaction analysis. The axi-symmetric numerical model is developed by using Finite Element Program Open-Sees PL18 to understand the soil pile interaction under the dynamic loading condition. The study concludes that the maximum displacement is less for C- Ø soil as compared to other two types C-soil and Ø -soil. Under the dynamic loading conditions, long pile is more sustainable than the Short rigid pile. Full article: pdf Centre for Earthquake Engineering |
