Özet:

Channel shear connectors are fairly new alternatives to the shear connectors. In this thesis two of the previously done experimental studies were simulated using FEM. First, push-out tests consisted of ten specimens which include European channel sections as shear connectors were modeled in ANSYS. The models with simplistic materials and 2D elements were analyzed. Analysis results were compared with the experimental results. Comparisons showed that, 2D models with bilinear materials were sufficient enough to provide practical ultimate capacity predictions. Second, full-scale beam test with channel shear connectors were simulated. Experiments included four specimens with differentiating connector numbers. The general aim was to investigate the partial and full composite action. 3D FE models were created with several concrete modeling approaches and difficulties in modeling were mentioned. One stable concrete model was found and selected for use. Experimental results and analysis result were compared. Also comments were made on model behavior. In conclusion, FE modeling details were reviewed and criticized.
