The concept of "Active Design" using field monitoring techniques to optimise  pile driving brings the advantages of a simple design, proven technology and associated with pile driving, modified from Massarsch and Fellenius (2008). This volume presents some advances in the analysis and design of deep Dr. Fellenius, Professor of Civil Engineering at the University of Ottawa from 1979 Analysis of driven pile bearing capacity results by static and dynamic load tests.

Static loading tests, O-cell tests, were performed on two long, strain-gage instrumented, bored piles in HoChiMinh City, Vietnam, where a series of twelve apartment towers were to be constructed. The test piles were constructed to 76 and 91 m depth and tested to maximum O-cell loads of 10 and 18 MN, respectively. For both piles, the O-cell level was placed at a depth of about 20 % of the pile CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Bengt H. Fellenius, P.Eng.

Fellenius and Siegel (2008) applied the neutral plane method to piles and drilled shafts in liquefied soil.

Design and Testing of Piles on a Telecommunications Project in Morocco @inproceedings{Kulesza2012DesignAT, title={Design and Testing of Piles on a Telecommunications Project in Morocco}, author={R. Kulesza and B. Fellenius}, year={2012} } The paper presents the findings to reaffirm the principle that design of a piled foundation requires the analysis of the interaction between load transfer, soil settlement and pile toe load movement response. The "Red Book" presents a background to conventional foundation analysis and design. The text is not intended to replace the much more comprehensive 'standard' textbooks, but rather to support and augment these in a few important areas, supplying methods applicable to practical cases handled daily by practising engineers and providing the basic soil mechanics background to those methods. +46(0)70-611 18 06 | jens.fellenius@sitelulea.se | linkedIn Civilingenjör inom teknisk design med inriktning mot produktion.
