10. What do you mean by economical span length with reference to bridges?
SECTION-B
11. ISMB 350@ 540 N/m is to join a column ISHB 300@ 588 N/m. The beam has to
transmit end reaction of 250 kN. Design a stiffened seat connection.
12. Differentiate between Deck type and through type truss bridges. Show various parts of
truss bridge with the help of a diagram.

13. Determine the flexural design strength of plate girder having simply supported
connection and continuous lateral support. Flange: 650 ? 50 mm, web: 2000 ? 12 mm,
span 16 m and only flanges resist bending moment.
14. Discuss the various functions of bearing?
15. Derive the expression for the economical depth of a plate girder. Assume moment is
resisted by flanges only.
SECTION-C
16. 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 = 250 kN.
Self-weight of crane girder excluding trolley = 200 kN.
Self- weight of trolley, electric motor, hook etc = 50 kN.
Approximate minimum approach of crane hook to the gantry girder = 1.2 m.
Wheel base= 3.5 m.
CIC distance between gantry rails = 15 m.
Span of gantry girder = 7.5 m.
Self-weight of rail section = 300 N/m.
Yield stress of steel = 250MPa.
17. Design a railway bridge for following data :
Type of bridge = Deck type plate girder bridge.
Span = 16m between centers of bearings.
Gauge - broad, single track, main line.
Distance between centers of plate girders = 2 m.
18. Explain the following :
a) Portal sway Bracing
b) Mill bent
NOTE : Disclosure of Identity by writing Mobile No. or Making of passing request on any
page of Answer Sheet will lead to UMC against the Student.
