According to IS 256: 2000, what is the minimum number of main steel bars that must be provided in a rectangular RCC column?

For M25 concrete with creep coefficient of 1.5, the long-term static modulus of elasticity (round off to the nearest integer, expressed in MPa) as per provisions of IS:456-2000 is______.

A concrete beam of rectangular cross section of 200 mmx400 mm is prestressed with a force 400 KN at eccentricity 100 mm. The maximum compressive stress in the concrete in N/mm² is

Which of the following is categorized as a long-term loss of prestress in a prestressed concrete member?

Torsion resisting capacity of a given RC section

Un-factored maximum bending moments at a section of a reinforced concrete beam resulting from a frame analysis are 50, 80, 120 and 180 kN-m under dead, live wind and earthquake loads respectively. The design moment (kNm) as per IS: 456-2000 for the limit state of collapse (flexure) is

A simply supported prestressed concrete beam is 6 m long and 300 mm wide. Its gross depth is 600 mm. It is prestressed by horizontal cable tendons at a uniform eccentricity of 100 mm. The prestressing tensile force in the cable tendon is 1000 kN. Neglect the self weight of beam. The maximum normal compressive stress in the beam at transfer in N/mm^2 is

A rectangular beam of width (b) 230 mm and effective depth (d) 450 mm is reinforced with four bars of 12 mm diameter. The grade of concrete is M20 and grade of steel is Fe500. Given that for M20 grade of concrete the ultimate shear strength τ_uc = 0.36 N/mm² for steel percentage, p = 0.25 and τ_uc = 0.48 N/mm² for p = 0.50. For a factored shear force of 45 kN, the diameter (in mm) of Fe500 steel two legged stirrups to be used at spacing of 375 mm should be
