The situations where the shear connection in a composite beam of steel and concrete can be subjected to concentrations of shear flow are listed and discussed. An account is given of relevant finite element (FE) analyses. The design rules given in the draft Eurocode fpr composite bridges, ENV 1994: 2, for shear connection near anchorages of Prestressing tendons, or at nodes in composite trusses, are shown to be radical simplifications of the results of these analyses. Reference is made also to similar situations, such as sudden changes of section, and shear connection in bowstring arches.
