Georgios Katsigiannis - Arup Research Engineer at University College, London - has organized a workshop for young practitioners and researchers at UCL on Tuesday 19 March 2013, staring at 16:30. The workshop is entitled:
Eurocode 7 and New Design Challenges
The workshop aims to encourage young
geotechnical engineers to engage with the new European safety codes and design
methodologies. Talks by international experts involved in the development of EC7 will be
followed by presentations from designers about their experience with EC7 compliant design. Talks announced so far include:
Some things Eurocode 7 doesn’t say, by Brian Simpson
Comparison of EC7 design approaches for numerical analysis of deep excavations, by Helmut Schweiger
Geotechnical design in seismic conditions, by Giuseppe Scarpelli
Design of top-to-down deep excavations for a metro-line in soft ground according to EC7 and German Recommendations, by Christos Vrettos
Attendees need to register their places - as explained on the following flyer.
The proceedings of the International Workshop on Safety Concepts and Calibration of Partial Factors in European and North Americam Codes of Practice, held at Delft University in December 2011, have now transfomed themselves into a book 'Modern geotechnical design codes of practice', available from Amazon and all good bookstores.
Divided into three main sections:
the book includes several papers devoted to Eurocode 7:
Implementation and evolution of Eurocode 7 by Andrew Bond (me)
Harmonisation of anchor design within Eurocode by Eric Farrell
Eurocode 7 and Polish practice: implementation of Eurocode 7 in Poland by Beata Gajewska
An explanation of characteristic values of soil properties in Eurocode 7 by Michael Hicks
Implementation of Eurocode 7 in German geotechnical design practice by Kerstin Lesny
Implementation of Eurocode 7 in French practice by means of national additional standards by Jean-Pierre Magnan and Sébastien Burlon
Implementing Eurocode 7 to achieve reliable geotechnical designs by Trevor Orr
Dealing with uncertainties in EC7 with emphasis on determination of characteristic soil properties by Hans Schneider and Mark Schneider
The safety concept in German design codes by Bernd Schuppener
British choices of geotechnical design approach and partial factors for EC7 by Brian Simpson
Dutch approach to geotechnical design by Eurocode 7, based on probabalistic analyses by Ton Vrouwenvelder, Adriaan va Seter, and Geerhard Hannink
There is now only one week to go before the next TC250/SC7 meeting in Brussels. This one is unusual, because we are dedicating the whole proceedings to discussion within Eurocode 7's Evolution Groups. Each group will get a 45 minute-long dedicated session to progress its ideas for the evolution of Eurocode 7.
More on this later, when I have prepared my slides...
I am currently attending a Coordination Group meeting of TC 250, in Ispra, Italy, where we are discussing TC 250's response to the Programming Mandate requested by the European Commission. This is a crucial moment in the development of this reponse - it's make your mind up time, in terms of what we ask for and the justification we ofer for it. More on this will follow as the meeting progresses...
I have just come back from a very interesting meeting with CARS, the Chinese Academy of Railway Sciences. Members of CARS have asked BSI China to advise them about implementation of the Eurocodes throughout the member states of CEN and various technical issues surrounding that. I was part of the BSI delegation asked to answer questions from CARS's experts.
CARS has been conducting research into limit state design, particularly in relation to track design, subgrade/foundation design, and tunnelling. I was able to explain some of the key benefits and difficulties of using Eurocode 7. Hopefully this will be the start of a very useful collaboration in this field.
We were treated to a fine traditional Chinese lunch and had the opportunity to discuss various technical matters in a very pleasant environment.
I am currently in Beijing, where I am part of a three man team delivering training courses on Eurocodes 2, 3, and 7 on behalf of BSI to one of China's power companies. These are detailed courses, not just overview/introductory courses.
While preparing this courses, I took the opportunity to read the Chinese ‘Code for Design of Building Foundations’, GB 50007-2002, and was pleasantly surprised how modern the code it. I am trawling it to see what ideas we could usefully incorporate into the next revisions of Eurocode 7!
The Association of Geotechnical and Geoenvironmental Specialists (AGS) has just published a Loss Prevention Alert No 52 on 'Eurocodes – Potential Legal Implications'
In it, the AGS warns:
... from the geotechnical practitioner’s point of view working to Eurocodes, at least at present, does not represent a clean break from British Standards. Furthermore the introduction of Eurocodes has resulted in a proliferation of new documents rather than a like for like replacement of the British Standards
We have just finished the 27th meeting of TC250/SC7 in the Hague, Netherlands. Our hosts, Fugro, provided a splendid venue for our 2 days of discussion - plus an excellent meal for all delegates at a restaurant in the ton last night.
This meeting was the last that Leendert Buth of NEN, the Dutch standards body, would be serving as Secretary of SC7. Leendert has been an important mainstay of the committee's work ever since I have know him (for 15 years, at least). On behalf of SC7, I presented Leendert with a leaving present - a framed and signed copy of the cartoon 'The Perfect European'.
The 26th meeting of TC250/SC7 will be held at The Hague, Netherlands on 22-23 March 2012. Discussion will focus on the work of SC7's 'Evolution Groups', which are already looking into what improvements can be made to EN 1997 in its next major revision, scheduled for 2018.
