RCC Structures Design Set 6

A continuous beam shall be deemed to be a deep beam if the ratio of effective span to overall depth, is

If the loading on a pre-stressed rectangular beam, is uniformly distributed, the tendon to be provided should be.

A pre-stressed concrete member is preferred because

If the maximum bending moment of a simply supported slab is M Kg.cm, the effective depth of the slab is (where Q is M.R. factor)

If jd is the lever arm and Æ©Ois the total perimeter of reinforcement of an R.C.C. beam, the bond stress at the section having Q shear force, is

The minimum head room over a stair must be

If the diameter of the main reinforcement in a slab is 16 mm, the concrete cover to main bars is

According to I.S. : 456 specifications, the safe diagonal tensile stress for M 150 grade concrete, is

For a circular slab carrying a uniformly distributed load, the ratio of the maximum negative to maximum positive radial moment, is

If the width of the foundation for two equal columns is restricted, the shape of the footing generally adopted, is
