خلاصه مقاله:
Due to unique geometry of castellated steel beams and existence of the web holes, estimation of shear load carrying capacity of these beams is rather different from traditional beams with solid webs. Shear capacity estimation of castellated beams becomes even more complicated when these beams are used in compositefloor systems due to contribution of the concrete slab. Herein, a numerical study is performed to assess the shear capacity of composite castellated beams by using nonlinear finite element (FE) method. A benchmark parametric FE model is created and validated comparing the test results. This comparison showed a goodaccuracy for the model. This model is used in the parametric study of shear response of composite castellated beams. Different FE models of these beams are analyzed and the obtained results show that the floor slab can have a considerable contribution in shear capacity of composite castellated beams
