The size effect in unnotched concrete specimens in bending causes a higher modulus of rupture compared with its axial tensile strength. To determine the axial tensile strength of concrete from flexural tensile tests, size effect coefficients are, therefore, required. Analytical equations have been derived in the past by the application of nonlinear fracture mechanics and finite element parametric...
Today, the development of innovative shear connectors for steel‐concrete composites is accompanied by a large number of experimental investigations, which are obligatory when proposing suitable design formula and carving out their limitations of use. Using the example of the so‐called pin connector, the present paper illustrates to what extent validated finite element models of novel shear connectors...
Die Querkrafttragfähigkeit von Spannbeton‐Fertigdecken (vorgespannte Hohlplatten) wird bei der Lagerung auf schlanken Trägern durch Beanspruchungen quer zur Spannrichtung herabgesetzt. In der Praxis stellt sich häufig die Frage, wann die Nachgiebigkeit eines Trägers bei der Bemessung der Platten zu berücksichtigen ist und wie sich eine Veränderung der Trägersteifigkeit auswirkt. Dieser Beitrag fasst...
