As per indian standard IS 456 : 2000, Where fckf_{ck} is the concrete compressive strength, the tensile strength of concrete is calculated as:​

  • A.

    ​0.7fck0.7 \sqrt{f_{ck}}​​

    ✓ Correct
  • B.

    ​0.87fck0.87 \sqrt{f_{ck}}​​

  • C.

    ​0.45fck0.45 \sqrt{f_{ck}}​​

  • D.

    ​0.57fck0.57 \sqrt{f_{ck}}​​

Answer & Solution

Correct option is A

As per IS 456:2000,
​Flexural tensile strength of concrete (fcr)=0.7fckWhere, fck=28 days’ characteristic compressive strength of concrete,which is the full strength of the concrete.\text{Flexural tensile strength of concrete } (f_{cr}) = 0.7 \sqrt{f_{ck}} \\[6pt]\text{Where, } f_{ck} = \text{28 days' characteristic compressive strength of concrete,} \\\text{which is the full strength of the concrete.}​​

Q4.

​A rectangular column 300 mm×300 mm size and 5 m long is restrained in position and direction at both ends.The recommended value of its effective length is ‾.\text{A rectangular column } 300\, \text{mm} \times 300\, \text{mm} \text{ size and } 5\, \text{m} \text{ long is restrained in position and direction at both ends.} \\\text{The recommended value of its effective length is } \underline{\qquad\qquad\qquad}.​​

  • A.5 m
  • B.4 m
  • C.2.5 m
  • D.3.25 m
    ✓ Correct

Answer & Solution

Correct option is D

As per IS 456: 2000
The recommended value of the effective length of the column effectively held in position and restrained in directions (or against rotation) at both ends is 0.65 times the length of the column.
The effective length of a given column (Leff) = 0.65 × L
The effective length of a given column (Leff) = 0.65 × 5 = 3.35 m
The effective length of column (Leff) = 3.25 m
