Question

How is the plastic torsion determined in the plastic hinge definition?


Answer:
The plastic rotation is determined automatically for each hinge, based on the previously determined cross-section and the member length. For this, the following formula is used:

$\varphi_{y,pl}=\frac{W_{y,pl}\cdot f_y\cdot l_b}{6\cdot E\cdot I_y}$
