gusset plate 12 mm thick with one line of 20 mm diameter bolts of grade 4.6. Use
steel of grade Fe 410.
Explain shear lag effect.
PART ‏تا‎

Answer any two full questions, each carries 15 marks.
Design a column to support a factored load of 1100 kN. The column has an
effective length of 7.0 m with respect to z-axis and 4.5 m with respect to y-axis
Use steel of grade Fe 410.
Design a suitable slab base for a column section ISHB 350@ 710.2N/m
supporting an axial load of 1000 KN. The base plate is to rest on a concrete
pedestal of M20 grade concrete. The load is transferred to the base plate by direct
bearing of column flanges. Use steel of grade Fe 410.
Design a built-up column consisting of two channels placed back-to-back to carry
an axial factored load of 1600 KN. Length of the column is 7m and the column is
restrained in position but not in direction at both ends. Also design the bolted
lacing system. Use grade Fe 410.
A conference hall 8m x 18m is provided with a RCC slab over rolled steel beams
spaced 3m centre to centre. Design the simply supported main beam supporting
concrete floor slab if thickness of concrete slab is 120mm and a wearing coat of
40mm thick is provided over the slab. Weight of concrete slab and wearing coat is
241/1.
List the different elements of a welded plate girder.

PART C

Answer any two full questions, each carries 20 marks.
A bracket plate is used to transfer the reaction of a beam to a column flange as
shown in Fig. The bracket plate is connected to the column flange by a 6 mm fillet
weld. Compute the maximum load that can be placed over the bracket plates at a

distance of 100 mm from the flange of the column section.
