Push-out tests on headed studs covered with UHPC
Headed studs are the most common shear connector in composite construction. Besides a high ultimate load the headed stud has to feature a high initial stiffness and a high ductility to allow an economic design. At the Institute of Structural Concrete at RWTH Aachen University numerous push-out tests have been performed to investigate the load carrying behavior of shear connectors and headed studs. Several modifications have been applied to the headed stud among them a cover made of ultra-high performance concrete (UHPC). This modification leads to an increase in the load carrying capacity as well as to an improvement in the ductility. The test program included studs with a diameter of 19 and 22 mm in normal strength (NSC) as well as in high strength concrete (HSC). This paper presents the main results of the experimental investigations.
