Distribution of shear intensity over a rectangular section of a beam, follows:
A. A circular curve
B. A straight line
C. A parabolic curve
D. An elliptical curve
If the shear stress in a R.C.C. beam is
A. Equal or less than 5 kg/cm2, no shear reinforcement is provided
B. Greater than 4 kg/cm2, but less than 20 kg/cm2, shear reinforcement is provided
C. Greater than 20 kg/cm2, the size of the section is changed
D. All the above
In a pre-stressed member it is advisable to use
A. Low strength concrete only
B. High strength concrete only
C. Low strength concrete but high tensile steel
D. High strength concrete and high tensile steel
In a simply supported slab, alternate bars are curtailed at
A. $${\frac{1}{4}^{{\text{th}}}}$$ of the span
B. $${\frac{1}{5}^{{\text{th}}}}$$ of the span
C. $${\frac{1}{6}^{{\text{th}}}}$$ of the span
D. $${\frac{1}{7}^{{\text{th}}}}$$ of the span
option C IS THE CORRECT ANSWER. The diameter of transverse reinforcement of columns should be equal to one-fourth of the diameter of the main steel rods but not less than 6mm.IS 456 cl 26.5.3.2 part C.2
Diameter of the lateral ties should be maximum of;
1) 1/4th of the main bar and
2) 6mm
So the answer here should be 6mm.
Lateral tie=1/4*longitudinal dia..
Or
=6mm... Which evere is max
So 1/4*16=4mm , so 6mm is max...
Correct answer is 6 mm
