Abstract
The composite bridge has consisted of different materials such as the girder to be steel or precast that connected with deck concrete slab using shear connectors for working as one. In the present study ALSABTEA bridge rehabilitation of the space of the bridge using the composite steel girder existing composite bridge constructed in Diyala-Iraq in 1981 that designed and constructed to behave as full interaction. Representation of composite steel bridge using finite element approach with different parameters to assess the doing of the composite bridge under the effects of static loading using actual dimensions and mechanical properties. The representation of channel shear connectors through elements of COMBIN39 provided simple and powerful modeling of the connectors in comparison with using elements of the 3D solid types. Examining the push-out test and comparing results with the model established by ANSYS proved the proposed numerical model could represent the shear connector's behavior. The difference is small (2.5% to 3.7%) between the model by using the representation shear connector as solid element and combined 39 also, the difference in the results of displacement is small (5%) between the experimental test and model established by ANSYS. The effect has been studied included. Partial and full interaction of Al-SABTEA Bridge under the effects of Static loadings applied at bridge based on Iraqi specification where the final assessment the results deflection within permissible limits according to all models.
Highlights
The term composite structure means that two or more different structural elements
Some recent contributions have taken the role of static loadings to the composite bridges
It was concluded that the slip in beams with uniform spacing of shear connectors was larger than the slip values in beams with variable spacing
Summary
It has connected to form one structural element such as composite bridge contains steel or precast girders and concrete slab. Burnet and Oehlers [5] suggested a design procedure for composite elements, and the variable was the degree of interaction and took into account the fracture that occurred in the shear connectors due to an increase in slip. Some contributions throughout the literature were implemented a three – dimensional numerical modelling to inspect the role of composite beam in term of load deflection curves as by Bachachi [8]. The current study tries to examine the full and partial interactions Al-Sabtea Bridge by implementing numerical modelling using finite element software “ANSYS”
