  4. Abstract:
  5. In this second part of the two companion papers an effective numerical model is proposed using finite element method to simulate the push-out test of channel shear connectors. The focus is on the shear capacity of channel shear connectors embedded in a solid reinforced concrete slab under monotonic loading. The model has been validated against test results presented in Part (I) and compared with data given in North American design codes. Parametric studies using this nonlinear model are performed to investigate the variations in concrete strength, channel dimensions and the orientation of the channel. The results show that the concrete strength, web and flange thicknesses of the channel and the length of the channel are significant parameters in determining the ultimate strength of channel shear connectors, whereas the height of the channel section is not a significant parameter. Also, changing the orientation of the channel causes a change in the stiffness and the ultimate strength of the shear connector. © 2008 Elsevier Ltd. All rights reserved
