- Pick up the incorrect statement from the following: Tensile reinforcement bars of a rectangular beam
- According to the steel beam theory of doubly reinforced beams
- The width of the flange of a T-beam, which may be considered to act effectively with the rib depends upon
- An R.C.C. lintel is spanning an opening of 2 m span in a brick wall. The height of the roof is 2.9 m above the floor level and that of the opening is 2.1 m above the floor level. The lintel is to be designed for self weight plus
- The maximum area of tension reinforcement in beams shall not exceed
- An R.C.C. beam of 25 cm width and 50 cm effective depth has a clear span of 6 meters and carries a U.D.L. of 3000 kg/m inclusive of its self weight. If the lever arm constant for the section is 0.865, the maximum intensity of shear stress, is
- Lapped splices in tensile reinforcement are generally not used for bars of size larger than
- After pre-stressing process is completed, a loss of stress is due to
- If a rectangular pre-stressed beam of an effective span of 5 meters and carrying a total load 3840 kg/m, is designed by the load balancing method, the central dip of the parabolic tendon should be
- If the size of a column is reduced above the floor, the main bars of the columns, are
- For initial estimate for a beam design, the width is assumed
- [A + (m - 1) ASC] known as equivalent concrete area of R.C.C. is given by

- The advantage of a concrete pile over a timber pile, is
- An R.C.C. roof slab is designed as a two way slab if
- The amount of reinforcement for main bars in a slab, is based upon
- The transverse reinforcements provided at right angles to the main reinforcement
- If p1 and p2 are mutually perpendicular principal stresses acting on a soil mass, the normal stress on any plane inclined at angle $${\theta ^ \circ }$$ to the principal plane carrying the principal stress p1, is
