Presented in a tile of BEHAVIOUR OF INCLINED HEADED STUD SHEAR CONNECTORS IN THE POSITIVE BENDING REGION OF THE COMPOSITE BEAM at the scientific meeting organized by Faculty of Mining, Geology and Civil Engineering, University of Tuzla, Bosnia and Herzegovina

ABSTRACT

The present investigation was focused on the headed stud shear connectors as application in inclined forms, and the hypothesis was global and local behaviour of the composite beam with inclined headed stud connector subjected to positive bending. A three dimensional non-linear Finite Element (FE) model of steel-concrete composite beam was developed with full and partial shear connections and verified with available experimental data of moment-deflection responses and failure criteria. A comparative study was then conducted with vertical and inclined sections of headed stud connectors such that a 12.1% increase in the ultimate moment capacity of the composite beam was predicted by using headed stud connectors as inclined section, which could be suggested as an innovative application that the inclined shear connector shows improved behaviour in terms of ultimate moment capacity and deformation of the full scale composite beam.
