Abstract

So far, numerous numerical studies have been conducted on the behaviour of Composite Reinforced Concrete-Steel (RCS) beam-to-column connections. However, the lack of studies regarding the steel joist-concrete girder connection has yet to be addressed through comprehensive finite element methods to get an understanding of the influential parameters. Hence, in this paper, composite connection of embedded steel joist in concrete girder is investigated with appropriate finite element software, namely, ABAQUS. The validity of the proposed model is examined by the comparison made with the test data presented in reference studies. Results indicate that maximum bending capacity of the connection is achieved when embedment ratio is 1.78. Moreover, double web angles in the embedment region significantly reduce the embedment length required to achieve the maximum bending capacity. Finally, damage analyses show that bending capacity of the concrete girder is slightly reduced in the connection zone.
