Course Name: DESIGN OF STEEL STRUCTURES

(Use of IS 800, IS 875, IS 883 are permitted. Assume suitable data wherever necessary)

Max. Marks: 100 Duration: 3 Hours
PARTA
Answer any two full questions, each carries 15 marks. Marks
1 a) What are the three classifications of loads as per IS 800: 2007 (3)

b) Two flat plates (Fe 410 Grade Steel), each 240 mm x 10mm are to be jointed (12)
using 20 mm diameter, 4.6 grade bolts, to form a lap joint. The joint is supposed
to transfer a working load of 200 KN. Design the joint and also find the efficiency
of joint.

2 a) An ISLC 350 @38.8kg/m is used to transmit a factored force of LOOOKN. The (10)

channel section is connected to a gusset plate 12 mm thick. Design a fillet weld if
the overlap is limited to 350 mm. Use slot welds if required.

0) A tie member in ೩ truss girder is 200 mm x 14 mm in size. It is welded to a 10mm (5)
thick gusset plate by a fillet weld. The overlap of the member is 350 mm and the

weld size is 6 mm. Determine the design strength of the joint

3 ஐ Design a single angle tension member subjected to a factored tensile load of (12)

270KN. The length of the diagonal is 3.0 m. The tension member is connected to a
