Questions

  1. Q1

    1. a)

      A Single ISA 90×60×6 @6.79 Kg/m is connected to 10 mm thick gusset plate at the ends with 5 numbers of 18 mm bolts to transfer tension. Determine the design tensile strength of angle section if the gusset plate is connected to the longer leg.

      [10]
    2. b)

      Explain various type of a bolted joint.

      [5]

  2. Q2

    1. a)

      Design the tie of a roof truss subjected to factored design load 280 kN using double equal angle section. The C/C length of intersection is 2.5 m. Assume angle is connected to 8 mm thick gusset plate by 4 number of M20 bolt.

      [10]
    2. b)

      Explain in detail gauge line, gauge distance, pitch, edge distance and end distance with sketch.

      [5]

  3. Q3

    1. a)

      Design a column section to carry axial compression of 750kN. The column has an effective length of 7.0 m with respect to x-x axis and 5m with respect to y-y axis.

      [8]
    2. b)

      A column 9 m long consisting 2ISMC 300 @35.8 kg/m spaced 220mm back-to-back to carry a factored load of 1200kN. The Column is restrained in translation but not in rotation at both ends. Design a suitable lacing system.

      [7]

  4. Q4

    1. a)

      Design a double angle discontinous strut to carry a factored load of 140kN. The Centre to Centre (C/C) length of strut is 2.6 m. The angle is placed back-to-back on opposite site of gusset plate.

      [8]
    2. b)

      Design a single angle discontinuous strut which is carrying factored load of unsupported 160kN. Length of member is 2.5 m. Assume fy = 250 MPa.Minimum two bolt are to be used for end connections. Use 20 mm dia. bolts of 4.6 grades. 
