Unbraced Frames – Sway Stability

Posted on by in Technical

In fact, the process is exactly the same as for unbraced frames, in that λcr, the measure of sway sensitivity, is calculated by applying the Notional Horizontal Forces (NHF) to the frame. The more interesting issues are the methods of dealing with sway-sensitive frames and the identification of the sway effects. David Brown reports.
