Abstract
This paper presents an experimental research program aiming at assessing the current code provisions of vmin. A large test series was carried out, by varying the reinforcement ratio and loading conditions, the minimum average shear stress that can cause shear failure of a specimen with different depth, concrete strength is determined. The three test series cover two types of concrete mixtures and a moderate structure depth range. In addition, the Eurocode and ModelCode 2010 provisions on vmin are discussed. They are compared with the test results. Recommendations on the present code expression are given.
