SECTION-A
- Design and sketch a footing for 1 brick thick wall 3m height, carrying a U.D.L. of 20 kN/m. Use traditional brick (230 mm x 115mm x 75mm). Safe bearing capacity (S.B.C.) of soil is 100 kN/m². Angle of repose of soil is 30°, soil density is 17 kN/m³. Use P.C.C. (1 : 4 : 8) as foundation concrete. Density of brick masonry is 19kN/m³. (10)
- Design a footing for a square column of 300 mm x 300 mm, having a height of 3.5 m. The safe bearing capacity (S.B.C.) of soil is 100 kN/m². Angle of repose of soil is 30°, soil density is 18 kN/m³; Use P.C.C. (1 : 4 : 8) as foundation concrete. Density of brick masonry is 19 kN/m³. (10)

SECTION-B
- A masonry retaining wall is 5m high with a vertical back. The backfill is horizontal with the top of the wall. The soil has an angle of repose of 30°. If the backfill has a density of 12kN/m³, calculate the magnitude of active pressure per meter length of wall and its line of action. (10)
- A masonry retaining wall is 4m high with a top width of 2m and base width of 3.5 m. The density of masonry is 21kN/m³ and density of soil is 15 kN/m³. Angle of repose of 30°. Find the maximum & minimum stress intensity. (10)
SECTION-C
--- Content provided by FirstRanker.com ---
- Design a brick column to carry an axial compressive load of 700 kN. The height of column is 3.5 m. Use conventional brick, cement sand mortar (1 : 4). (10)
- Design a brick masonry wall using traditional brick to support an axial load of 100 kN/m. Height of brick wall is 3m and its length between cross wall is 4m. (10)
SECTION-D
- Design a timber beam using Kali wood to carry a U.D.L. of 12kN/m over a span of 4m. (10)
- Explain check for shear deflection & bearing. (10)

SECTION-E
- Design a compressive member for a wooden roof truss to carry an axial compressive load of 65kN. The span of member is 2.5m. Use teak wood. (10)
- What are the uses of timber trusses? Explain any 5 shapes of roof trusses with neat diagram of each. (10)
