Or A 75mmx50mmx8mm angle is to be connected to a gusset plate by 6mm fillet welds at the extremities of the longer leg. Design the weld connection corresponding to the full tensile strength of the angle. Assume shop welding. 12. Design side wall and floor slab only for a RC circular tank resting on the ground for a capacity of 500 m3. The depth of storage is to be 4 m. Free board is 200 mm. Use M20 and Fe410 grade steel. Or Design a steel circular elevated water tank with hemispherical bottom for a capacity of 250 m3. The height of the tank bottom above the ground level is 8.7 m. The tank is supported over eight columns and is situated at the Allahabad railway station. Height of cylindrical shell shall be 0.8 times the diameter of the tank. 13. Design a R.C. slab culvert for an NH to suit the following data: Carriage way 2 Lane, Footpath 1m on either side, Clear span of bridge 6 Thickness of wearing coat 80 mm, Width of the bearing 400 mm. Use M20 and Fe415. Loading condition IRC70R (Class AA) tracked vehicle. Or Describe about IRC specifications and loadings. 14. Design stem and toe for a cantilever retaining wall to retain earth embankment with a horizontal top above ground level: Density of earth 18 kN/m3, Angle of internal friction, 30o, SBC of soil 200 kN/m2, Coefficient of friction between soil and concrete 0.6. Adopt M20 and Fe415. Or Design stem and counter fort for the counter fort retaining wall based on the following data: Height of the wall above ground level 6m SBC of soil 160kN/m2 Angle of internal friction 330 Density of soil 16 kN/m3 Spacing of counter forts 3m c/c Adopt M20 and Fe415.

15. Write step by step procedure for the design of purlin. Or Design a self-supporting chimney of 30 m height. The diameter of the cylindrical shell is 2 m at the top. The chimney has a 100 mm thick brick lining supported on the shell. Take a uniform wind pressure intensity of 1.5 kN/m2 throughout the height. Assume uniform values of permissible tensile and compressive stresses as 120 N/mm2 and 90 N/mm2. Design of base plate, lugs and anchor plates are not necessary.
