Sketch the deflection profile and reinforcements details of cantilever retaining wall.
[5 marks]Draw typical bending pattern, shear force and bending moment diagram for combined rectangular footing. And also locate the critical section.
[5 marks]Design effective depth of a rectangular footing for two columns Aand Bcarrying loads of 600 kN and 800 kN respectively. Column Ais 300 mm X 300 mm and column Bis 400 mm X 400 mm in size. The centre to centre spacing of the columns is 3.5 m. The SBC of soil is 180 N/mm2. Use M 20 concrete and Fe 415 grade steel
[10 marks]Write various forces acting on retaining wall with sketch and describe active earth pressure by Rankine Theory for (i) Dry or moist backfill with no surcharge and (ii) Submerged backfill
[6 marks]Explain the stability condition for cantilever retaining wall with diagram for (i) Stability against overturning (ii) Stability against sliding and (iii) Maximum pressure at base and no tension at base
[6 marks]Write down the steps to calculate retaining wall.
[8 marks]Fix the basic preliminary dimensions of various components including stem of a cantilever retaining wall to retain the earth of height 7 m above lower ground level and carry out stability checks. Also design the stem and do the structural detailing. Take SBC of soil = 210 kN/m2 Ø = 300 , µ = 0.5, Unit weight of soil = 15 kN /m3 . Use M 20 grade of concrete and Fe-415 grade.
[20 marks]Fix the basic dimension and design the top dome of Intze type container elevate water tank to store 3 lakh litre water. Draw the Sketch. If the height of container is 15 meter, Wind load 2 kN/ m2 & Soil Bearing Capacity of 200 kN/ m2. M20 & Fe 415 grade of steel.
