2. (a) Give the details of various rolled steel section with suitable diagram.
(b) A tension bar 100 mm x 100 mm is to carry a load of 150 kN. A specimen of the same quality steel cross-section area 800 mm² was tested in the workshop. The maximum load carried by the specimen was 400 kN. Find the ultimate tensile strength, factor of safety in the design and the gauge length.
3.(a) Explain in brief various types of loads to be considered in the design of steel structure.
(b) A portal frame consists of two hinge supported column of 4 m height separated by a beam of span 5 m and loaded up to collapse with downward uniformly distributed load of 15 kN/m and lateral point load of 50 KN at left beam column junction. Find the plastic moment of resistance if it is of uniform strength.
4. (a) Differentiate between fillet weld and butt weld. Under which conditions fillet weld is preferred?
(b) Why is lacing provided in the columns?
5.(a) A tie bar 100 mm x 16 mm is welded to another plate. It is subjected to factored pull of 300 kN. Find the minimum overlap required if 8 mm site fillet welds are used. Assume any missing data.
(b) Write down the steps for the design of axially loaded columns.
6. A simply supported beam of span 6 m supports a reinforced concrete slab. The compression flange of the beam is restrained due to its connection with the slab. The beam is subjected to a dead load of 25 kN/m and an imposed load of 20 kN/m. Design the beam.
(7.) Design a grillage foundation with 1-sections for a column having a load of 5000 KN. Column is provided with a base plate of size 700 mm × 800 mm. Take bearing capacity of the soil as 200 kN/m². Assume any missing data.
8. Design a built-up tension member to carry a factored force of 340 kN. Use 20 mm diameter black bolts and gusset plate of8 mm thick
9. The line diagram of a steel truss of 9 m span, angle of slope 20° is shown in the figure below. The roof sheeting is of corrugated GI sheets of unit weight 150 N/sq.m of plan area. The truss supports purlins of unit weight 75 N/sq.m of plan area. The weight of bracing used may be taken as 20 N/sq.m of plan area. The spacing of trusses is 4 m and height of eaves 4.5 m. If the building is of medium permeability, determine (a) dead load, (b) wind load and (c) live load at various panel points of the truss. Assume design wind pressure as 1500 N/mm2:
