Abstract

Investigation of the behavior of composite beams with different types of shear  connectors (spirals and bent bars) extends to include the comparison between the  theoretical study and the experimental results of such types of beams.  
In this paper, a proposed technique for predicting the shear resistance of the  spirals as shear connectors in the composite beams is presented. In this- technique, the  behavior of the connectors in the elastic and the plastic ranges is analyzed. Hence, a  proposed formula to predict the design shear resistance of the spirals is suggested.  The comparison between the suggested formula and the experimental results showed a  good agreement between them.  
Moreover, a comparison between the theoretical and the experimental results for the tested composite beams with spirals and bent bars as shear connectors is carried out with respect to ultimate loads. ultimate moment and deflections.  
The common type of shear connectors as bent bars is compared with spiral connectors  as well. A discussion for the given formulae of die beat bar shear resistance in both  Egyptian and European (EC4) codes together with the experimental results is  conducted which may lead to the modification of the Egyptian formula.  
The comparison between the present theoretical work and the experimental  results has shown good agreement.
