A per the stress block defined in IS 456-2000, the limiting depth of neutral axis in a flexural member having effective depth ‘d’ reinforced with Fe 550 grade steel in tension side is

Coefficient of shrinkage of high-grade concrete for post tensioned work is

An RCC beam is of size 900mmx300mm. It is subjected to a moment of 150 kNm and torque of 30 kNm at limiting conditions. The equivalent bending moment is

The percentage of reinforcement in case of slabs, when high strength deformed bars are used is not less than

The limiting depth of neutral axis of a beam section 250 × 500 mm cross section with M25 grade concrete and Fe 250 grade steel as per limit state method is

(Assume concrete cover to be 40 mm)

Shear key is provided when factor of safety in which of the condition is less than the permissible.

What will be a Net upward pressure unreinforced concrete wall footing. If thickness and load carrying capacity of a wall is 72 cm and 600 kN per meter (SBC = 200 kN/m²) Assume weight of footing is 10% of load on the wall

A concrete beam of 10 m effective span and 1m effective depth is supported on 500x500 mm² columns. If the total uniformly distributed load on the beam is 10 MN/m, the design shear force as per working stress method is

The design horizontal seismic coefficient is 0.083 and seismic weight is 1020 KN. The design base shear is:
