Bruckner)The ESIS-Technical Committee 9 on Concrete was established in 1990 and has met seven times. A proposal was put to European and extra-European laboratories entitled "Scale effects and transitional failure phenomena of reinforced concrete beams in flexure" which lead to several positive responses. <P>The central topic discussed by the committee was that of the minimum reinforcement in concrete members. The minimum amount of reinforcement is defined as that for which "peak load at first concrete cracking" and "ultimate load after steel yielding" are equal. In this way, any brittle behaviour is avoided as well as any localized failure, if the member is not over-reinforced. In other words, there is a reinforcement percentage range, depending on the size-scale, within which the plastic limit analysis may be applied with its static and kinematic theorems. <P>Carpinteri, Ferro, Bosco and El-Katieb propose a LEFM model, according to which reinforcement reactions are applied directly on the crack surfaces and a compatibility condition is locally imposed on the crack opening displacement in correspondence with the reinforcement. The theoretical model is found to provide a satisfactory estimate of the minimum percentage of reinforcement that depends on the scale and enables the element in flexure to prevent brittle failureElectronic reproduction.Amsterdam :Elsevier Science & Technology,2007.Mode of access: World Wide Web.System requirements: Web browser.Title from title screen (viewed on Aug. 2, 2007).Access may be restricted to users at subscribing institutionsFlexureCongressesConcrete beamsTestingCongressesCarpinteri, AlbertoReferexhttp://www.sciencedirect.com/science/book/9780080430225An electronic book accessible through the World Wide Web; click for informationTable of contents onlyhttp://catdir.loc.gov/catdir/enhancements/fy0601/99018029-t.htmlPublisher descriptionhttp://catdir.loc.gov/catdir/enhancements/fy0601/99018029-d.html.b1364978403-03-2224-01-08991003213739707536Minimum reinforcement in concrete members1213209UNISALENTOle02624-01-08m@ -engne 00
