    Abstract:

Applications: One of the most important and most commonly encountered problems in geotechnical earthquake engineering is the evaluation of ground response. Ground response analysis is used to predict site natural periods, assess ground motion amplification, provides ground motions for development of design response spectra, evaluate potential for liquefaction, and to determine the forces induced due to an earthquake which can lead to instability of earth and earth slopes. To estimate the ground response of soil one shall have correct soil model which represent its dynamic properties. For this purpose, field tests (SPT, Seismic down hole tests) and laboratory tests (cyclic triaxial tests and geotechnical tests) will be carried out for soil sites from northern India.
Advantages: For this purpose, field tests (SPT, Seismic down hole tests) and laboratory tests (cyclic triaxial tests and geotechnical tests) will be carried out for soil sites from northern India. Using the laboratory and field test results, it is proposed to develop a model for dynamic deformation characteristics for northern Indian sites. The model proposed will be validated by applying recorded time history of bedrock and compares its free field response with the recorded free field time history. Also liquefaction assessment will be carried out using the site characteristics data and site response study results. The effects of soil strain, terrain properties, water table and earthquakes on Peak ground motion will be studied.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
