1. A compression member consists of double angles placed with short legs back to back. This member is connected. to the same side of a gusset plate of 12 mm thickness. Design the member to carry a load of 300 kN having effective length 3 m. Use Fe 250 steel.

Design a riveted connection for a tensile member which consists of a 60 x 40 x 6 mm ISA angle connected by the longer leg to a gusset plate 6 mm thick. The axial load carried by the member is 60 kN.

Determine the tensile strength of 100 x 75 x 10 mm angle connected to the gusset plate by 20 mm diameter power driven rivets connected to longer leg. Take Oat 150 MPa.

3. A welded bracket transmits a vertical load of 150 kN at a distance of 350 mm. A 12 mm thick plate is connected to the column flange by horizontal and vertical welds (Fig. 1). Determine the size of fillet weld, if allowable stress in the weld is 100 N/mm^2.

4. Design an I-Section purlin for a roof truss. The design data is as follows

Spacing of Truss =5.0 m

Inclination of Roof

Spacing of Purlins m c/c

Wind Pressure kN/m^2

Roof is covered with G.I. sheet whose dead load is 0.3 kN/m^2.

5. Design a beam having effective span of 8.0 m. This beam carries a uniformly distributed load of 30 kN/m over its length including its self-weight. The compression flange of the beam is laterally supported throughout. Check the beam for shear and deflection.

6. Design a built up column using lacing carrying an axial load of 1100 kN. Its length is 7 m and it is effectively held in position at both ends and restrained against rotation at one end only. Assume a yield stress of 250 N/mm^2.

Discuss the various forces acting on steel chimneys.

Discuss briefly end bearing for steel bridges.

Explain briefly forces in a gantry girder.

8. Design a column base for a column of ISHB 300 section. It carries an axial load of 350 kN and a bending moment of 50 kN-m in the plane of the web. The bolts are having a pretension of 150 N/mm^2. Assume allowable bearing pressure on footing as 4 N/mm^2.
