Study Of Deck Bridge Culverts Under Different Mix Proportions And Span Configurations

Abstract

Culverts Are Required To Be Provided Under Earth Embankment For Crossing Of Water Course Like Streams, Nallas Etc. Across The Embankment, As Road Embankment Cannot Be Allowed To Obstruct The Natural Water Way. This Paper Deals With The Study Of Design Parameters Of Box Culverts Like Effect Of Co-efficient Of Earth Pressure, Angle Of Dispersion Of Live Load And Depth Of Cushion Provided On Top Slab Of Box Culverts. Present Study Has Been Performed To Know How Design Of IRC-112 Differs From IRC-21 And An Attempt Is Made To Study Undefined Parameters Of IRC: 112- 2011 Such As Span To Depth (L/d) Ratio. Present Study Is Performed On Design Of RC Slab Culvert Using “working Stress Method” Using “IRC: 21-2000 And Limit State Method Using IRC: 112-2011” Code Specifications. It Is Observed That In Working Stress Method, The Allowable L/d Ratio Is 13 And In Limit State Method, The L/d Ratio Of 20 Is Most Preferable. This Paper Deals With The Study Of Design Parameters Of Box Culverts Like Effect Of Co-efficient Of Earth Pressure, Angle Of Dispersion Of Live Load And Depth Of Cushion Provided On Top Slab Of Box Culverts. This Paper Presents An Overview Of The Design Construction, And Laboratory And Field Testing Of A Box Culvert Bridge Reinforced With Glass FRP (GFRP) Bars. Here An Effort Has Been Made To Shows The Economic And Effective Design Can Be Achieved By Doing Finite Element Analysis Element Analysis Of A Box Culvert Whose Concept Can Be Used For Large Structural Design As Well.
