Asingle span solid slab bridge is to be designed according to the AASHTO LRFD. If the slab (bridge) span =10m, the slab thickness, h= 500 mm, f. 25 Mpa, fy=400 Mpa, CONCRET unit weight Yc=24 Kn\m2, asphalt thickness=100 mm with 22 KN\M3, the bridge total width= 10m, design the interior strips by filling the following blanks. 1- The width of the interior strip if one lane is loaded, Ent= m. 2- Assuming the effective interior strip width, Eint=3000mm, complete the following calculations per 1m of the interior strip). a-The dead load moment, Mpc = Kn.m\m b-The wearing surface moment Mow = Kn.m\m C-The moment caused by lane loading, M LANE ...............Kn.m\m d- The moment caused by tandem loading, M TANDEM=........ Kn.m\m e-The live load moment including dynamic allowance, M U+LM = f-The design moment, Mu Kn.m\m g-The required area of steel A,-. .mm²\m h- The required transverse steel A s, transverse mm²\m The student must send all answers and calculation. 20 mark 10m 12m
