title = "Punching shear strength of RC flat slabs provided with shear-heads at interior connections to steel columns",
abstract = "This paper investigates the structural performance of cruciform shear-head systems fully integrated in RC flat slabs at interior connections to steel columns. The test results from a series of six large scale members of which two were provided with headed shear studs, offer a direct evaluation of the full load-deformation behaviour of the specimens as well as the ultimate punching shear strength attained prior to failure at the critical slab perimeter outside the shear-head region. Particular focus is given to the influence of the shear-head and headed shear stud reinforcement to the member kinematics and failure characteristics. The experimental findings coupled with shear field analyses enable the development of analytical models that depict the rotational response and flexural strength as a function of the shear-head characteristics, and support the definition of a shear-head dependent control perimeter required for punching shear strength assessments. Additionally, analytical design expressions that adopt the fundamentals of Model Code 2010, which account for the characteristics of the shear-head system, are proposed and their results capture in a more realistic manner the shear-head influence on the punching shear strength of RC flat slabs in such hybrid configurations in comparison with strength predictions from current conventional RC design methods.",
