Question Paper is Given Below:

Full Marks: 100 | Pass Marks: 45 | Time: 3 Hrs
Candidates are required to give their answers in their own words as far as practicable. The figures in the margin indicate full marks. Students are allowed to use IS 800-1984/1994, IS 875-1987, IS 883-1970/1994 and Steel section books.

Attempt all the questions.

1. a) An angle cleat is connected to a column flange 16 mm thick by 3-20 mm pds rivets. Find the end reaction of a beam that the angle cleat may support if the thickness of the angle is 10 mm. [7]
b) Design a fillet welded joint between two plates of size 200 X 10 mm and 250 X 10 mm. Also sketches the details. [8]

2. Design a tension member using two equal angles placed back to back on both sides of 12mm thick gusset plate to carry an axial tension of 220KN. [15]

3. Design a built up column section for an axial load of 1000KN with two I-sections along with battering. The effective height of column is 5m. [15]

4. Design a column splice for column section SC 250 and SC 220 carrying a load of 500 KN. Also sketches the details. [15]

5. Determine live load and wind for a steel roof truss of a cinema hall at Nepalgunj. The span of truss is 25m and its pitch is 1/4. Height of eaves above the ground level is 7m.Assume suitable data if necessary as per IS 800 – 1984. [15]

6.Design a framed connection between a beam section MB 400 and a column section SC 250 if the beam is to transmit an end reaction of 150 KN. [15]
OR
a. Explain about design of web plate and web stiffeners in plate girder. [9]
b. State the assumptions in the theory of riveted joints. [6]

7. Design a timber solid column which is subjected to a compressive load of 18KN and bending moment of 1.2KN-m. The member is 2m long and timber is deodar wood. [10]
