Topic 8

Question 1

Structural members that support transverse loads and are therefore subjected primarily to flexure, or bending.

Answer 1

Beams

Question 2

Said to have formed at the center of the beam, and his hinge along with the actual hinges at the ends of the beam constitute an unstable mechanism

Answer 2

Plastic hinge

Question 3

Structural analysis based on a consideration of collapse mechanisms is called

Answer 3

Plastic analysis

Question 4

The moment required to form the plastic hinge, can easily be computed from a consideration of the corresponding stress distribution

Answer 4

Plastic moment capacity

Question 5

Prevents lateral translation, should be applied as close to the compression flange as possible

Answer 5

Lateral bracing

Question 6

Prevents twist directly; it can be either nodal or continuous, and it takes the form of either cross frames or diaphragms

Answer 6

Torsional bracing
