PART 13
Answer any two full questions, each carries 15 marks.

Design a column 10 m long to carry a factored axial load of 1100kN.The column
is restrained in position but not in direction at both ends. Design a batten system
for the column. Assume that the two channels are kept back to back.
Explain the failure modes of axially loaded columns
Determine the design load capacity of the column ISHB 300@577 N/m if the
length of the column is 3m and its both ends are hinged.
What are the cross section classification defined in IS 800-2007 based on
slenderness of plate elements?
Design a simply supported beam of 10m effective span carrying a total factored
load വ്‌ 60kN/m. The depth of beam should not exceed 500mm. The compression
flange of beam is laterally supported by floor construction. Assume stiff end
bearing is 75mm.
PART C

Answer any two full questions, each carries 20 marks.
Determine the design forces in the members of a Fink type roof truss for an
industrial building for the following data. Overall size of building : 48 x16m.,
C/c spacing of trusses: 8m , Rise of truss :1/4 of span , Self weight of purlins :
318 N/m., Height of columns : 11m. Roofing : A © sheets (171N/m?), Location :
Agra.
Derive the expression for calculating the force F in a bolt subjected to a factored
load P at an eccentricity e. The line of action of the load is in the plane of the
bolted connection and the centre of gravity of the connection is the centre of
rotation.

The trusses for a factory building are spaced at 6 m c/c. and the purlin is spaced at
