Paper Details

The paper presents the comparison of the absolute structural parameters of the I-section concrete girderbridge of varying slab thickness 365mm to 815mm under AASHTO HS-20 loadings and IRC Class A loadings. The FEASoftware Staad pro have been used to analyse the deck girder bridge. In this work the RC deck is modelled as the simplysupported beam and the bridge deck spanning in the one direction. The Bridge deck has a persistent length as 10m andwidth as 12m. Different deck Thickness of the concrete bridge deck have been considered (365mm to 815mm). Themoving live loads have been assigned to the concrete deck bridge as per specifications mentioned in AASHTO and IRC:6codes. Class A loadings have been considered from Indian Code IRC: 6 Section: II and HS-20 Loading have beenconsidered from the AASHTO LRFD HS-20. The study indicates that the values of the structure parameters of the Isection concrete girder bridge under AASHTO HS-20 Loadings are more when compared with the Class A loading ofIRC. Thus there is a need for a more uniform and realistic principles and standards of loads in future.
