Question

1.
An I-beam shown below is made of steel. The beam may treated as perfectly elastoplastic with a yield
stress (equal to the proportional limit) of 36 ksi. The plane of bending is about the x-axis.
Determine the maximum elastic moment and the maximum plastic moment that the beam can support.

Answer 1

An I-beam shown below is made of steel. The beam may treated as perfectly elastoplastic with a yield stress (equal to the proportional limit) of 36 ksi. The plane of bending is about the x-axis.

Determine the maximum elastic moment and the maximum plastic moment that the beam can support.
