The main reason for providing number of reinforcing bars at a support in a simply supported beam is to resist in that zone
A. Compressive stress
B. Shear stress
C. Bond stress
D. Tensile stress
Answer: Option D
Solution (By Examveda Team)
In a simply supported beam, the primary purpose of providing reinforcement bars at the support is to resist tensile stress.At the supports, the top fibers of the beam experience compression, while the bottom fibers experience tension.
To resist this tension, reinforcing bars (tensile reinforcement) are provided at the bottom near the supports.
This reinforcement ensures that the beam can safely handle the tensile forces, preventing cracking or failure in that zone.

In symmetrically reinforced sections, shrinkage stresses in concrete and steel are respectively
A. Compressive and tensile
B. Tensile and compressive
C. Both compressive
D. Both tensile
Critical section for shear in case of flat slabs is (adopting standard notations)
A. At a distance of effective depth of slab from periphery of column/drop panel
B. At a distance of $$\frac{{\text{d}}}{2}$$ from periphery of column/capital/drop panel
C. At the drop panel of slab
D. At the periphery of column
A. depends on as, only
B. depends on aCbC only
C. depends on both crst and acbc
D. is independant of both ast and acbc where d is the effective depth, ast is per-missible stress in steel in tension and ocbc is permissible stress in concrete in bending compression.
The diameter of ties in a column should be
A. More than or equal to one fourth of diameter of main bar
B. More than or equal to 5 mm
C. More than 5 mm but less than one-fourth of diameter of main bar
D. More than 5 mm and also more than one-fourth of diameter of main bar
tensile stress is correct
