Q9. Explain in brief about bracings.
Q10. What do you mean by economical span length with reference to bridges?
SECTION-B
Q11. Design a section of plate girder to carry a uniformly distributed load of 1000kN over a
span of 10m. A full lateral support is provided to the compression flange. Provide
stiffeners if required.

Q13. Discuss the various functions of bearing.
Q14. Derive the expression for the economical depth of a plate girder. Assume moment is
resisted by flanges only.
Q15. Write down the steps of design of stringers.
SECTION-C
Q16. Design a Gantry girder without lateral restraint along its span, to be used in an industrial
building carrying a overhead travelling crane for the following data :
Crane Capacity = 300 kN.
Self-weight of crane girder excluding trolley = 250 kN.
Self-weight of trolley, electric motor, hook etc = 55 kN.
Approximate minimum approach of crane hook to the gantry girder = 1.15 m.
Wheel base = 3.5 m.
CIC distance between gantry rails = 15 m.
Span of gantry girder = 7.4 m.
Self-weight of rail section = 350 N/m.
Yield stress of steel = 250MPa.
Q17. Design a railway bridge for following data :
Type of bridge = Deck type plate girder bridge.
Span = 18m between centers of bearings.
Gauge - broad, single track, main line.
Distance between centers of plate girders = 2m.
Q18. Explain the following :
a) Mill bent
b) Cross-girder
NOTE : Disclosure of Identity by writing Mobile No. or Making of passing request on any
