Question

What is non-sway frame?

(a) transverse displacement of one end of member relative to other end is not effectively prevented

(b) longitudinal displacement of one end of member relative to other end is not effectively prevented

(c) transverse displacement of one end of member relative to other end is effectively prevented

(d) longitudinal displacement of one end of member relative to other end is effectively prevented

I got this question in an online quiz.

Question is taken from Methods and Assumptions of Analysis topic in chapter Structural Analysis, Loading and Load Combinations of Design of Steel Structures

Answer 1

Right option is (c) transverse displacement of one end of member relative to other end is effectively prevented

The best explanation: In non-sway frame, transverse displacement of one end of member relative to other end is effectively prevented. Example : in triangulated frames and trusses, in plane stiffeners is provided by bracings or by shear walls, etc.
