A

True

23
Q

The difference between diagonal bracing and K- bracing between steel columns is that:

A

False

27
Q

A

Braced Frame

28
Q

In a braced-frame steel structure, the braced bays may be provided on what?

A

May be provided on the exterior façade, the interior of the building, or both.

29
Q
