This paper deals with performance of composite connection of embedded steel joist in concrete girder with appropriate numerical analysis. The proposed model is validated by experimental data presented in reference studies. performance of connection of steel beam to concrete girder are, however, assessed through different approaches including influences of embedment ratio, double web angle, size of web angle, tie distances, studs, steel beam with flanges cut in connection zone and plates in web of steel beam. As a result, an appropriate embedment ratio is offered to achieve maximum bending capacity of the connection. Using double web angles at the embedment region, however, reduce the ratio. Damage analyses show that bending capacity of the concrete girder slightly reduces in the connection zone. Better performance of steel plate installed in web at connection zone is also observed among composite connection approaches. Using low tie distances at connection zone increases capacity by 10%. Performance of double web angle is, further, compared under hysteretic and monotonic loadings. The ratio of L/h in hysteretic behavior of connection was 20% higher than that of monotonic loading.
