For counterfort Retaining wall, If I is clear distance between the counterfort and P is the intensity of soil pressure. The slab is designed for Bending Moments :

In water retaining structures upto 100 mm thickness the minimum reinforcement in walls floors and roofs in each of the two directions at right angle shall have minimum area equal to :

In a retaining wall, keyed expansion and contraction joints should be provided at an interval of:

An overhead water tank of capacity 40,000 litres is considered as a :

While designing the isolated square column, if p' is the net upward reaction, a is the length of one side of the square footing of column of side b and d is the effective depth of footing, then the punching shear is given by :

A rectangular beam simply supported over a span of 6 m is provided with tensile reinforcement only. The beam 200 mm wide and 365 mm deep (effective) consists of 4 no. 16 Ф, the beam carries a load of 8 kN/m inclusive of self weight and m=13. The maximum Bending moment :

 A RC beam 25 cm x 50 cm in section has a clear span of 5 m and carries a load of 3000 kg/m it is reinforced with 8 bars of 12 mm dia at the bottom and depth of N.A. below the top is 23 cm. The per bend stress is 10 kg/cm². The number of bars that should be bent to take the diagonal tension would be :

In case of RC footing on soils it is usual to keep a minimum overall depth at the edges equal to :

Critical section for shear in case of flat slab is at a distance of :

The approximate loss of prestress due to the slippage of anchorage in long span prestressed concrete is generally in the range of :
