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. Briefly explain different types of failures in welded joints with a neat sketch.
Design a suitable fillet weld to connect web plate to flange plate and flange plate to cover plate
of compression flange in plate girder shown in Figure 1. The size of web plate is 1000x10mm
thick and flange 300x16mm and cover plate 600x10mm. The maximum factored shear applied is
800kN. Use shop made fillet weld (Use steelstrength fu 410MPa and fy250MPa
Figure 1
2. What is meant by stiffened and un-stiffened connections of beam column. Show the arrangement
in both the cases with neat sketch?
Design a suitable site made fillet weld to connect tension member with gusset plate as shown in
Figure 2. Check the strength of weld at failure.

UNIT II
3. A ISLB350@49.5kg/m beam carries total load of 180kN (UDL over a span of 6m. The beam
connected to column section ISHB250@54.7kg/m by site made fillet weld on both sides . Design
the joint and detail connecting system with neat sketch.
A 10mm thick bracket plate used to transfer reaction 100kN (factored) at eccentricity 150mm
from column flange. Design a suitable site made butt weld. (Use steel strength fu 410MPa and
fy250MPa shown in Figure 3.
Figure 3
4. Design an I section of fixed beam which carries UDL load 8kN/m over a span of 8m. Check the
section for serviceability conditions? Assume the top compression flange laterally restrained(Use
steel strength fu 410MPa, andfy=250MPa).
Design a simply supported steel beam which carries UDL load 10kN/m over a span of 6m. Assume
the compression flange is laterally unrestrained with bearing length 100mm (Use steel strength
fu 410MPa, and fy=250MPa). Check the section for serviceability conditions?
UNIT III
5. Enlist the loads acting on the structure and write on live load calculations for roof truss.
type roof truss of 18m span and length 36m proposed to construct for an industrial building.
The spacing between the trusses are 6m c/c ,subjected to uniform wind intensity 1.5kN/m2
normal to the roof. Assume the height of building up to eave strut 8m and pitch of roof 1in4.Use
GI roof covering with no openings. Design the Truss elements include geometry of type truss
components of the roof truss and with a neat sketch.
6. As per the I.S code what are the limitations to be considered for the design of compression and
tension members during the design of bridge truss?
A Pratt type railway truss bridge-single track broad gauge type ,(through type) of 11 equal
panels each of length 5m and depth 5m, carries UDL live load 30kN/m and dead load 20kN/m
respectively. Design the following elements at mid span
i. Top chord member
ii. Bottom chord member

UNIT IV
7. Discuss wind loads and wind effect on truss girder bridge.
A through type Pratt truss girder of pedestrian bridge span 20m, width 3m subjected to UDL
3kN/m2 is subjected to uniform wind pressure 2kN/m2. The walk way constructed with RCC
slab is 150mm thick. Design the following elements and detail with neat sketch?
i. Longitudinal truss girder
ii. Bottom bracing system
8. Briefly explain Janssen's theory for the design of bunkers?
Design a circular steel Silo of height 16m and internal diameter 6m to store cement of bulk density
of 18kN/m3 and angle of internal friction 25o?
UNIT V
9. Write step wise procedure followed in the design of bins.
Explain with neat sketch the design of Silo's by Airy's method.
10. Classify types of bins and explain the factors affecting design of bins.
Write the procedure followed in the design of Bunkers and explain bin storage and bulk storage.
