Question

What is sway frame?

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

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

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

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

This question was addressed to me during an online exam.

My query is from Methods and Assumptions of Analysis topic in section Structural Analysis, Loading and Load Combinations of Design of Steel Structures

Answer 1

Right answer is (d) transverse displacement of one end of member relative to other end is not effectively prevented

The best I can explain: In sway frame, transverse displacement of one end of member relative to other end is not effectively prevented. Such members and frames occur in structure which depend on flexural action of members to resist lateral loads and sway.
