SECTION-C
7. Design RCC Tee beam to suit following data :
Clear width of roadway = 7.5 m
Span (centre to centre of bearing) = 16 m
L.L = IRC class AA tracked veh.
Average thickness of wearing coat = 80 mm
Concrete mix = M-25 grade
Steel = Fe 415 grade HYSD bars.
Compute the design moments and shears and design the deck slab main girders and cross
girders and sketch the typical details of reinforcement.
8. Design a suitable masonry abutment for girder bridge. The angle of internal friction of
the retained material is 45?. An approach reinforced concrete slab is provided to the
bridge so that the effect of surcharge may be neglected. The angle of friction between soil
and masonry is 30?. Height of the abutment below road level is 6.0 m. The positive earth
pressure in front of the abutment is to be neglected. Density of masonry is 2 t/m
3
, density
of concrete is 2.4 t/m
3
& density of soil is 1.8 t/m
3
.
9. a) Why is corrosion prevention important in maintenance of prestressed concrete
bridges?
b) List the equipment needed for bridge inspection.
