Week 3 Challenge

Aim and Introduction -

For the I Girder bridge to be designed for the following data, the centre to centre distance of piers along the width of the bridge deck is 26m , Span of the bridge is 25m, Pier height is 10m, Apply the IRS railway loads and model in Staad pro and perform the structural analysis

Dead Load of Structure -

1) Height Pier is 10 mtr and Size of Pier consider 2.5 mtr X 2 mtr =(2.5*2*10)*2.5MT*4 nos= 125 MT

2) Portal Beam Size on top of Pier 2 mtr x 2mtr = 2*2*26*2.5 MT*2 = 520 MT

3) Dead load of I Girder - ((1.2x0.25x25)+(1.25x0.75x25))*8*2.5 = 618.75 MT

4) Deck Slab - 25*26*0.3*1*2.5= 487.5 MT

Total Dead Load on Foundation = 125+520+618.75+487.5 = 1751.25 MT

Subgrade modulus - 10 KN/M2
