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. What are the different types of failures in tension members and explain it with neat sketches.

Design an eccentric loaded welded connection between a column ISHB300@58.8kg/m and a
bracket 10mm thick. Adopt maximum size of the shop welds possible. The load and the welds are
in the same plane. The vertical and horizontal load at the top of the bracket at service are 200kN
and 40kN (acting outwards) respectively. The distance of the vertical load from the centre of the
column is 600mm. The grade of the structural steel is Fe410. Check the safety of the connection.

4. Explain the design procedure for laced columns in builtup column sections.
Check the adequacy of the HSFG bolts of M16 with 10.9 property class bracket connection which
is to resist a factored load of 190kN (Load perpendicular to line of bolts) at an eccentricity of
150mm from face of the column. Numbers of bolts in one line are seven with pitch and end
distances 65mm and 45mm respectively. Assume grade of steel as Fe 590Mpa.

UNIT III
5. Design the members AB and AC at joint A of a roof truss, of slope 26°34' apart for the following
data in given Table 1.
Table 1
Member Length Compressive force Tensile force
AB 2.3 m 75kN 55kN
AC 1.8 m 60kN 80kN
Design the welded connection at joint A. Use tubes of grade Yst 210 for the data given in Table
1.
6. Design the members of a roof truss shown in Figure 1 for the factored forces indicated.
Design the connection at left support and sketch the details. All the forces indicated are factored
load as shown in Figure 1.

UNIT IV
7. With the help of neat sketches explain the types of truss bridges.
A simply supported steel joist of 4m effective span is laterally supported throughout. It carries a
total uniformly distributed load of 40kN(inclusive of self weight). Design an appropriate section
using steel of Fe410.

8. Write short notes on different loads acting on the roof truss.
Design an I section purlin, for an industrial building situated in the outskirts of Hyderabad
to support a galvanised corrugated iron sheet roof for the following data(use ISWB150@166.77

Spacing of truss c/c=6m
Span of truss=12m
Slope of truss=300
Spacing of purlins c/c=1.5m
Intensity of wind pressure=2kN/m2
Weight of galvanised sheets=130N/m2
Grade of steel= Fe410
UNIT V
9. Explain with neat sketch the design of silo's by airy's method.
Design a strut in a roof truss for the following data
Length of strut=2.234m
Factored compressive force=50kN(due to DL and LL)
Factored tensile force=17.8kN(due to DL and WL)
Grade of steel=Fe410
Grade of bolts=4.6
Bolt diameter=20mm
10. Explain the factors affecting design of bins by considering different design parameters.
Write the procedure followed in the design of Bunkers as per Indian standards.
