Event report: Adding value to structural projects through the application of fib resources, April 11
(L-R) Chris Hendy, Ian Feltham, Jon Shave
This evening technical meeting showed how fib bulletins help solve engineering design issues.
About 50 engineers attended the event, which was introduced by Professor Steve Denton (Chairman fibUK) and included presentations by representatives of fibUK member companies.
Ian Feltham of Arup showed the audience his well-used copy of Model Code 90 and welcomed the imminent arrival of model code 2010, referring to how fib and the former FIP and CEB publications had for many years been key documents to inform many technical design guidance notes circulated within Arup. These covered topics such as use of dowels, bond of reinforcement, strut and tie action, high strength concrete, creep behaviour and use of fastenings.
Chris Hendy of Atkins explained how fib bulletins had assisted his work on the complex replacement of the stay cables on Penang bridge which included careful assessment of fatigue and required use of FRP strengthening locally of the concrete deck. He referred to bulletin 30 and noted that it had significantly informed the contents of the UK National Annex to EN1993-1-11 and how it had been used to assess the fatigue effects in the stay cables. He particularly noted how guidance given in bulletins goes beyond current codes and standards in assisting to solve complex design issues.
Jon Shave of Parsons Brinckerhoff described complex assessments of bridge half-joints where Bulletins 61 and 45 had enabled significant enhancement of assessed capacity and reduction in strengthening over that obtained using more conventional methods of analysis. This had direct benefit to the client and also removed the need to restrict loading on the bridge joints.
Questions and discussion followed the three presentations and the audience was informed about the forthcoming publication of MC2010 and the explanatory background papers, shortly to be published in the journal Structural Concrete.
