Q3) A double cover butt joint is used to connect plates 14mm thick. Design the bolted joints and its efficiency.
Q4) Design a compound column to carry an axial load of 650 kN. The column consists of two channels placed back to back and laced together. Take effective length =5 m.
Q5) The plates of a tank 8mm thick are connected by a single bolted lap joint with 20mm diameter bolts at S0mm pitch. Calculate the efficiency of the joint. Assume Fe410 plate and grade 4.6 bolts
Q6) A Column ISHB 350@ 674N/m carries an axial load of 850KN. Design suitable slab base using M20 Conc. mix.
SECTION-C

Q7) Design a simply supported beam of 8 m span carrying a reinforced concrete floor capable of providing lateral restraint to the top compression flange. The total u.d.l. is made up of 100 kN dead load including self-weight and 150kN live load. In addition, the beam carries a point load at mid span made up of 50 kN dead load and 50kN imposed load. Assume stiff bearing length of 75 mm
Q8) Write short notes (any two) :
- Design of Flanges and Web of Plate girder.
- Design of Gusset base.
- Economical spacing of Roof Truss

Q9) Design an I-section Purlin for an industrial building to support a galvanized corrugated Iron sheet given:
Spacing of the trusses : 6m
Inclination of main rafter : 30°
Spacing of Purlin : 1.5m
Weight of purlin : 1.5m
--- Content provided by FirstRanker.com ---
Weight of corrugated sheeting : 130N/m’Live Load = 0.6 KN/m’
Wind Load = 1.8 KN/m’
Yield stress of steel = 250MPa
NOTE : Disclosure of Identity by writing Mobile No. or Making of passing request on any page of Answer Sheet will lead to UMC against the Student.
