RCC Structures Design Set 1

Distribution of shear intensity over a rectangular section of a beam, follows:

If the shear stress in a R.C.C. beam is

In a pre-stressed member it is advisable to use

In a simply supported slab, alternate bars are curtailed at

If L is the effective span of a R.C.C. beam which is subjected to maximum shear qmax at the ends, the distance from either end over which stirrups for the shear, are provided, is

Total pressure on the vertical face of a retaining wall of height h acts parallel to free surface and from the base at a distance of

In a pre-stressed beam carrying an external load W with a bent tendon is having angle of inclination ? and pre-stressed load P. The net downward load at the centre is

If the ratio of long and short spans of a two way slab with corners held down is r, the actual reduction of B.M. is given by

An R.C.C beam of 25 cm width has a clear span of 5 metres and carries a U.D.L. of 2000 kg/m inclusive of its self weight. If the lever arm of the section is 45 cm., the beam is

The minimum clear cover for R.C.C. columns shall be
