01 Apr 2010TL;DR: In this paper, the state-of-the-art type analysis and design techniques for behavior of such sub-structural system during seismic events are discussed and the role of the design codes in India with a com- parison to such activities around the world using international design codes is dis-cussed.
Abstract: Structural integrity of underground constructions or sub-structures like foundations, anchors, basements, piles, piers, abutments, retaining walls, subgrade of railway, highway, airport runway etc. are important concern for the engineers and researchers in the entire world to advance on the infrastructural developments of any country. Several historical giant earthquakes all over the world had always put the researchers and engineers to the new challenge for developing advanced and new techniques of design and construction to maintain the structural integrity of the infrastructural systems. In this paper, the state-of-the-art type analysis and design techniques for behavior of such sub-structural system during seismic events are discussed. In this connection, the role of the design codes in India with a com- parison to such activities around the world using international design codes is dis- cussed. The importance of soil profile with seismic characterization is highlighted. Benefits of the recently proposed and validated pseudo-dynamic approach over the conventional pseudo-static approach have been revealed. The mitigation technique such as the use of geosynthetic materials for the stability and integrity of such sub- structures during seismic events is also discussed. The latest trends in research and practice for design of sub-structural systems in India and other countries are revealed.

TL;DR: In this article, a self-learning algorithm was used to estimate the load transfer curves from a database of uninstrumented pile-loading tests using a selflearning algorithm, an inverse analysis framework capable of handling ill-posed problems.
Abstract: An attempt is made to estimate the load transfer curves from a database of uninstrumented pile-loading tests using a self-learning algorithm, an inverse analysis framework capable of handling ill-posed problems. The aim is to extract useful but masked information about load transfer encapsulated in the observed load-deformation response of axially loaded piles. From the results obtained, the estimated load transfer curves tend to produce better load deformation models compared with the predictions based on conventional t-z curves, thus indicating that the self-learning algorithm has succeeded in extracting the load transfer data indirectly from uninstrumented pile tests.
