“…Figure a shows the possible shear transfer actions acting on a free body, the shape of which is defined by the critical flexural‐shear crack. As shown in recent studies, the occurring shear transfer actions can be determined adequately with the aid of detailed full‐field photogrammetric measurements of the displacements taking place inside the shear field. Linking well‐known constitutive laws for concrete and steel with the measured crack kinematics of critical shear cracks or with strain recordings allows the contributions of several shear transfer actions to the shear strength to be estimated.…”

“…Bei den Versuchen von Leonhardt (; S. 20; Versuch 5) ergaben sich beispielsweise Abweichungen von bis zu 20 %. Die unvermeidlichen Streuungen resultieren u. a. aus der Inhomogenität des Verbundwerkstoffs ‚Stahlbeton‘ und dem damit verbundenen unterschiedlichem Verlauf des maßgebenden Schubrisses .…”

“…Hierdurch können Verzahnungskräfte im Riss aktiviert werden, die jedoch mit zunehmender Öffnung der Risse kleiner werden. Untersuchungen zur Risskinematik an schubbeanspruchten Balken sind beispielsweise in dokumentiert. Eine schematische Darstellung des beschriebenen Zusammenhangs kann Bild entnommen werden.…”
