Abstract

Composite Bridges are mainly used in the construction of various flyovers to minimize the traffic flow. Composite highway bridges are subjected to many dynamic actions with different magnitudes due to the action of different types of vehicles. Depending on the magnitude and intensity and many other adverse effects the structural system and performance may compromise and that may lead to a reduction of the expected bridge life. A composite (steel concrete) bridge having dimensions of 12.50 m roadway width and concrete deck thickness of 0.23 m, having a span of 40.0 m was investigated in this paper. The model was developed for the composite bridge dynamic analysis and was implemented in the MIDAS-CIVIL program which has finite element method simulations. Along with steel concrete composite model a conventional bridge model was also modelled using same dimensions. After applying all loads as per Indian Standard Codes various results were discussed in the paper.
