A concrete pedestrian girder supports cantilevered Steel cross beam. The factored load pedestrian on one side of the girder is equal to 30 kN/m. the girder span 20m and 900mm wide are supports capable of resisting the torsional effects. A maximum Aggregate size 20mm has been satisfied; 12mm bar are used for the stirrups and 25 mm bar for flexural reinforcement. Design the girder where fc 30 MPa, fy 400MPa. w=30 kN/m 500 mm 900 mm
