Q4) State and explain classification of cross section by bending stress
distribution.
Check the adequacy of ISHB 400 82.2 kg/m to carry a factored axial
compressive load of 700 kN at an eccentricity of 150 mm about major
axis cindering section strength. The effective length of column is 3m.[6]
Q5) An ISLB 550 86.3 kg/m has been used as a simply supported beam
over 8 m span. Determine the safe uniformly distributed load w so that
the beam can carry safely in flexure. Assuming compression flange is
restrained throughout the span against lateral buckling.
Explain web buckling and crippling with suitable sketches.
OR
Q6) Design suitable I section for simply supported beam of span. 6m. The beam
is subjected to a dead load of 30kN/m and a live load of 40 kN/m. The beam
is laterally unsupported throughout the span. Also check for serviceability.[16]
Q7) An ISLB 350 49.5kg/m transmit an end reaction of 400 kN under
factored load to the web of ISWB 500 @95.2kg/m.Design bolted framed
connection.
Explain beam to beam and beam to column connection with suitable
sketches.
OR
Q8) A simply supported welded plate girder of an effective span of 20 m subjected
to uniformly distributed load 25 kN/m throughout the whole span excluding
the self weight of plate girder. Assume compression flange laterally supported
throughout the span. Design cross section of plate girder, check for shear
buckling of web and shear capacity of end panels.
Q9) Determine the design forces in the members AB,AL and BL of a truss as
shown in Fig. 9.The design wind pressure is 900 N/m2. The truss is covered
with AC sheet and the center to center spacing of truss is 6m.

Q10)Design cross section of simply supported gantry girder to carry electric
overhead traveling cranes with following data.
Span of gantry: 4m, Span of crane girder: 15m, Crane capacity:320 kN, self
weight of crane girder excluding trolley 40 kN, Minimum hook approach:
1m, center to center distance between wheels:3.2 m and self weight of rails
300N/m.
