Paper Title
A COMPARATIVE STUDY OF LIVE LOADS FOR A BRIDGE DECK WITH IRC AND AASHTO CODES
Abstract
The paper presents the comparison of the absolute structural parameters of the I-section concrete girder bridge of varying slab thickness 365mm to 815mm under AASHTO HS-20 loadings and IRC Class A loadings. The FEA Software Staad pro have been used to analyse the deck girder bridge. In this work the RC deck is modelled as the simply supported beam and the bridge deck spanning in the one direction. The Bridge deck has a persistent length as 10m and width as 12m. Different deck Thickness of the concrete bridge deck have been considered (365mm to 815mm). The moving live loads have been assigned to the concrete deck bridge as per specifications mentioned in AASHTO and IRC:6 codes. Class A loadings have been considered from Indian Code IRC: 6 Section: II and HS-20 Loading have been considered from the AASHTO LRFD HS-20. The study indicates that the values of the structure parameters of the I- section concrete girder bridge under AASHTO HS-20 Loadings are more when compared with the Class A loading of IRC. Thus there is a need for a more uniform and realistic principles and standards of loads in future.
