Experimental studies on shear connection between steel and lightweight concrete using studs

Abstract

This contribution describes Standard Push-Out Tests carried out at University of Minho (UM) and the Single Push-Out Tests performed at the Institute of Structural Concrete at RWTH Aachen University using high strength lightweight concrete (HSLWC). The test configuration follows the EC4 recommendations and repeats some dispositions referred by other authors. The experimental studies carried out at RWTH and UM include tests on studs with diameters of 19, 22 and 25 mm and also tests on studs of 19 mm diameter, which are grouped in pairs. The purpose of the experiments conducted is to determine the load-bearing capacity as well as the deformation capacity of commonly used headed shear stud when using high strength lightweight concrete. The results from these tests are compared to those from the tests performed with high strength normal weight concrete (NWC).
