Answer ONE Question from each Unit
All Questions Carry Equal Marks
All parts of the question must be answered in one place only
UNIT I
1. What are the advantages and disadvantages of welded connections
An ISA 100×100×10mm carries a factored tensile force of 100kN. It is to be jointed with a 12mm
thick gusset plate. Design a high strength bolted joint when Slip is not permitted and Slip is
permitted. Use M16 bolts of grade 8.8 and Fe410 steel.
2. Discuss the shear failure of black bolts in bearing type bolted connections with sketches.
Design a welded connection [three sides] for the tension member ISA 100 × 65 × 8mm subjected
to 150 kN service load [Field weld].
UNIT II
3. A beam ISLB500@75kg/m transmits end reaction 120kN and moment 90kN-m to the flange of
the column ISHB 400@82.2kg/m. Design a suitable shop made fillet weld.
Design a stiffened seat angle connection of fillet weld of a beam ISMB 500@86.9kg/m which
transmit an end reaction of 250kN to the web of column ISHB300@63kg/m. Detail the joint with
neat sketch?
4. Design the I section Purlin of roof with the following data. Spacing of roof truss 4m, spacing
of purlins 1.5m, pitch of roof 1in weight of GI roof sheeting 125 wind load intensity
normal to roof 12004N/m2. Check the serviceability conditions?
A tension member of roof truss carrying tensile force 30kN meets the principle rafter carrying
compressive load 100kN at right angle. The panel length along the principle rafter is 2.4m.
Design both the members and welded joint for the members. (Assume allowable stress in fillet
weld 80MPa?
UNIT III
5. A Pratt type roof truss for factory building of span 30m and pitch 1in4 proposed to construct
at Delhi plain terrain -category-2). The spacing of the truss 5m c/c and the length of building
60m. Design the following truss components?
i. Purlin
ii. Principle rafter
Page 1 of 2
Design members AB, AC and joint A of a roof truss, 26°34' apart for the following data.
Table 1
Member Length Compressive force Tensile force
AB 2.3 m 75kN 55kN
AC 1.8 m 60kN 80kN
Also design the welded connections at joint A. Use tubes of grade Yst 210.
6. Explain different types of bracing systems used in the design of truss girder bridges? Explain
their functionality?
Explain different types of forces to be considered in the design of truss bridges?
UNIT IV
7. With the help of neat sketch explain the types of truss bridges.
Design a rectangular steel bunker 12m length 6m width supported on eight columns four along
each side of length) to store coal density 8 kN angle of internal friction 35o . Height of
vertical portion 6m and height of hopper 2m. Provide 600x600mm hopper. Detail the elements
and connections?
8. Mention different type of forces to be considered in the design of bins?
Write short notes on different loads acting on the roof truss.
UNIT V
9. Explain with a neat sketch the design of silo's by airy's method
What are the material properties for design of storage hoppers?
10. Explain the factors affecting design of bins
Write the procedure followed in the design of Bunkers.
