Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2014-07-01 Abstract The results of an investigation of splitting of joints of [1] are used for a discussion of design methods and as necessary answer on comments and for confirmation of the extended fracture mechanics theory which accounts for the part of the external energy which is needed for plastic dissipation at the dowels, (which cause the crack opening). It is shown that exact theory always is needed to give a precise description of fracture behavior for a real calculable reliability in all circumstances. It further is shown that applied cohesive zone models, J-integral, and finite element solutions, are questionable and always need to be explained and controlled by theory. Important is, that these empirical fitting procedures are not able to fit to any relation, as follows from exclusion by the “lack of fit” test. Contrarily, limit analysis theory shows a precise fit (with a coefficient of variation of 10%) to the theory equation and delivers a conclusive confirmation of criticized design rules of Eurocode 5.
