FE MODELLING FOR CAPACITIES OF HEADED STUD SHEAR CONNECTORS IN COMPOSITE STEEL BEAMS WITH SLABS CONCRETE

This study discusses the overall performance of the behavior the shear stud in the composite steel beam. The work has been modeled by using ANSYS APDL program. Under of the influence of lateral horizontal pressure. The analyzed structure is a composite of beam-slab. The beam section is (254 X 254 X 73 kg/m) with slab of (1600 mm length, 1200 mm width and 150 mm height) and 6 headed studs 19mm diameter with 100 mm high featuring a single row of pointed studs spaced at 150 mm intervals. First, the study was placed on 200 mm from the end of the slabs on both sides. Headed studs and the value of the limited load are the most relevant dimensions for the aims of this study. One parameter was changed which was the load value. The resulted composite steel was analyzed for each change in the parameters. The results were compared to those from the experimental which revealed a possible alternate analysis that included the selected changes. Besides, the Von-mises stresses and stress intensity have been studied. It was found through structural analysis that there were stresses in the area of the studs which they are resistance to horizontal slips caused by lateral pressure loading. Four composite steel were evaluated at each parameter and were checked with the other factors. For this aim a utilizing parametric analysis software using ANSYS. Language of Design (APDL) was constructed to examine the behavior of the structure.
