2. (a) (i) Classify the plastic, compact, and semi-compact sections. (i) Consider a T-section of flange 100 mm x 10 mm and web 150 mm x10 mm. Calculate shape factor, plastic moment, and reserve of strength. Use Fe 410 grade of steel.
(b) Design a double-cover plate butt joint using hexagonal head bolt ISO 4016-M 24×70-grade 5-6 property class C to connect two flats of size 350 mm x16 mm for maximum efficiency. Assume plate material as E250.
3. (a) A water tank is made with 10 mm thick plates. The plates are jointed by a lap joint using 18 mm dia bolts of grade 4-6 property class C at a pitch of 60 mm. Find the efficiency of the joint.
(b) The tension member of a bridge truss consists of a channel ISMC 300. Design a fillet weld connection of the channel to a 10 mm gusset plate. The member has to transmit a factored force of 800 kN. The overlap is limited to 350 mm. Use field welding.
4. (a) Differentiate between type-1 and type-2 bracket connections.
(b) A beam ISMB 350@514 N/m has to transmit a factored end reaction of 200 kN to the flange of a column ISHB 250@536-6 N/m. Design a stiffened seat connection using shop-welded fillet welds.
5. (a) Discuss in detail the design procedure for the built-up batten column.
(b) A column section ISHB 400@759-29 N/m is to be spliced. Design the splice plates and the connections using M20 bolts of product grade C and property class 4-6. Assume the column has machined ends. The factored design loads are the following:
Axial load over the column = 525 kN
Shear force 225 kN
Bending moment = 75 kN-m
6. A column of effective length is 9-3 m. It is subjected to an axial factored load of 1500 kN. Design the lacing system with site-welded connections for two channels back-to-back.
7. (a) Discuss in detail the stiffened and unstiffened seat connections.
(b) A beam ISMB 400@604-3 N/m has to transmit a factored reaction of 160 kN to the flange of a column ISHB200@392-4 N/m. Design a framed connection. Assume site welding.
8. A welded plate girder of 20 m span is subjected to the BM of 4000 kN-m and the SF of 800 kN (both are factored loads). The girder is laterally restrained. Use steel of grade Fe 410 and assume yield stress to be 250 MPa. Design the plate girder and check for bending strength.
9. (a) Why is a bracing system provided in the trusses? Why are sag rods required in roof trusses?
