Part III. Calculation: An assembled RC simply supported T-beam bridge is shown in the Fig. 1. One front wheel load is applied on the beam. The pavement is asphalt concrete as thick as 3cmfunit weight 23kN/m and 9cm thick of C30 concrete under layer unit weight: 24kNm), the flanges' unit weight is 25kN/m. And the load level is Highway-I. The main technical indexes of vehicle load are listed in Table land the effective work width of the deck is shown in Fig. 2 Note: According to the code, the height of the slabr-120em, the width of the rab by 180mm, the height of pavement layer H-120mm (asphalt concrete pavement 30mm+ concrete under layer 9mm), and the height of the rib h130mm thus: When calculating bending moment: -L-*-(1600-180+120-1540mm: When calculating shear force: -L-1600-180-1420mm. Impact factor ist Required: (a) Calculate the bending moment of the slab (b) Take picture or scan your homework, and send to jinoyishtahun.
