Practice Question: Shear Modulus of a Structural Steel Member

---

---

Solution

Refer to PE Civil Reference Handbook Section 1.6.2.4 for the Shear Stress-Strain relationship.

The shear modulus is as follows:
\[\text{G=} \frac{E}{2(1 + \nu)} \\\]
where:

Modulus of Elasticity: \(E= 29000\ ksi\)

Poisson's Ratio: \(\nu =0.2\)

\[G= \frac{29000}{2 \times (1+ 0.2) } = 12083\ ksi \\\]
