Determine panel point dead load, imposed load and wind load for the truss as show in Figure 1. Assume design wind pressure as 1200 N/m 2 , use A.C. Sheet and the C/C spacing of truss is 6 m. Assume self-weight of purlin as 120 N/m.
Q7
- a)[4]
Explain in brief IS provisions for length and spacing of intermittent weld.
- b)[14]
A simply supported welded plate girder of an effective span of 20 m subjected to factored uniformly distributed load 43 kN/m throughout the span including self weight. Assume compression flange laterally supported throughout the span. Design cross section of the plate girder.
OR- a)
Q8
- a)[4]
- b)[14]
A Simply supported welded plate girder is designed for the span of 24 m. It is subjected to a shear force of 2300 kN and bending moment of 20700 kNm. A section used for plate girder to carry above load is as given below - Flanges - 780mm wide and 50 mm thick Web - 16 mm thick and 2600 mm deep Design intermittent welded connection between flange and web. Also design end bearing stiffener.
