A simply supported beam of span 8 meter having a rectangular cross section of 500mm*250mm.The beam is prestressed with force 1500KN at 50mm eccentricity below the neutral axis .What is the position in mm below the neutral axis at centre of span where tensile stress is zero? Considering the self weight of material of beam is 26KN/m.

A rectangular column section of 250x400 mm reinforced with 6 steel bars of Fe500, each of 25mm diameter. Concrete Mix is M3o. Axial load on column section with minimum eccentricity as per IS 456-2000 using limit state method can be applied upto:

A pretensioned prestressed concrete sleeper 300 mm wide and 250 mm deep is prestressed using 5 wires of 7 mm diameter located near the soffit. The effective cover being 40 mm. The initial stress in the wires is 1256 N/mm². Assuming the modular ratio as 6, the percentage loss of stress due to elastic deformation of concrete is

An RC column 500 mm x 500 mm is reinforced with 4 bars of 25 mm diameter, placed at a cover of 50 mm to the centre of steel bars. The maximum and minimum stresses (in N/mm²) in concrete if the column is subjected to a load of 500 kN at an eccentricity of 50 mm about one of the axes is [Use M 15 concrete and m = 18]

The elemental composition analysis of the water supply is tabulated as follows:
