(2)    Assume suitable data wherever necessary and specially mention it.

(3)    Figures to the right of each question indicate full marks.

(4)    Use of IS 875, and IS 800 is permitted.

(5)    Programmable calculator is not allowed.

1 (a) A Ship breaking company, at Calicut wants to construct 4 a wear house of 25m x 60m at Calicut ship yard. Design a 'Pratt' type roof truss, its spacing, number of panel points, rise etc for a wear house. The height of truss up to eaves level is 12m.

(b) Calculate the dead load, and the live load for a 10 selected roof truss in Q. 1(a).

OR

(b) Calculate the wind load per panel point for the    10

above truss. If the total opening is 25% of wall area.

2 Design a discontinuous double angle truss member,    12

having a 4.0m length. Which is subjected to a compressive load of 250 kN. The member is connected by two rivets at ends.

3    An ISA 150x75x8 is connected by a shorter leg, to the 10mm thick gusset plate by 12mm diameter rivets. Calculate the tensile load carrying capacity of a truss member. If the length of a member is 2.5m.

4    Write true or false with proper reason.    12

(1)    Performance of steel structure is better than that of a concrete structures in an earthquake zone.

(2)    Load carrying capacity of compression member, depends on the slenderness ratio.

(3)    An effective area of a member governs the load carrying capacity in compression.

(4)    Permissible deflection for a beam is span / 300.

5    Design a filleted welded end connection for a tie    8 member ISA 150x150x10, subjected to the 200kN tensile load. Take the permissible stress of weld as 100 N/sq.mm.

OR

5    Draw a plan and a section of a gusseted based steel    8 footing.

6    Design a steel beam AB' - shown in Fig. 1.    14 The thickness of R.C.C. slab is 120mm. The live load

on a slab is 5 kN/sqm. Also check the section for deflection and shear.

7    Design a column, which is subjected to an axial load of 12 1200kN. The height of a column is 4.0m, and one end is fixed in a position as well as in rotation while another end is only fixed in position but not restrained against rotation.

8    Design a slab based footing for a column designed in 10 Q. 7. The permissible stress for concrete and soil are

4 N/sq mm and 200 kN/sq m.

9    Draw a proper stiffened seated connection between the 8 web of ISMB column and ISMB beam.
