ISRO Draughtsman Civil Mock Test - 8 - Question 1

The value of Poisson's ratio of concrete is

Detailed Solution for ISRO Draughtsman Civil Mock Test - 8 - Question 1
The value of Poisson's ratio of concrete is 0.2.

Poisson’s ratio of concrete is the ratio of transverse strain to longitudinal strain in a concrete specimen subjected to axial loads. The longitudinal strain and vertical strain are produced due to concrete volume reduction under compression load. Volume reduction of the concrete specimens is the result of crushing small aggregate sizes due to exerted loads. Poisson’s ratio of concrete is a constant for determining the stress and deflection properties of structures such as beams, plates, and shells
