SECTION-B
11) Design a butt joint to connect two plates 240 ? 12 mm (fy = 230 N/mm2) using ordinary
M20 bolts. Arrange the bolts to give maximum efficiency.
12) Calculate moment of resistance of RCC beam 300mm ? 500mm reinforced with 4 bars of
20 mm diameter of Fe415 steel. Use M20 concrete.
13) What is the role of Structural engineer in Structural Engineering?
14) Design a rectangular beam for simply supported span of 6.1m, carrying a superimposed
load of 28 kN/m inclusive of its self weight. Use M20 concrete and Fe415 steel. Take
width of beam as 300 mm.
15) Difference between one way and two way slab.
SECTION-C
16) Design a slab over a room 8m ? 4m as per IS code. The edges of the slab are simply
supported and corners are not held down. Take live load as 3.2 kN/m2. The slab has a
bearing of 180mm on the supporting walls. Use M20 concrete and Fe415 steel.
17) Design a built up column 9.8m long to carry an axial load of 730 kN. The column is
restrained in position but not in direction at both the ends. Provide single lacing system
with riveted connections. Assume fy = 250 MPa.
a) Design the column with two channels placed back-to-back.
b) Design the column with two channels placed toe-to-toe.
18) Design a beam of 5.5m effective span, carrying a uniform load of 20 kN/m if the
compression flange is laterally supported. (Assume fy = 250 N/mm2)
NOTE : Disclosure of Identity by writing Mobile No. or Making of passing request on any
