Subject: A Practical P-Delta Analysis Method for FR and PR Frames
| A Practical P-Delta Analysis Method for Type FR and PR Frames ERIC M. LUI In the stability design of frameworks, attention must be given to the additional moment developed as a result of member (P-δ) and frame (P-∆) amplification effects from compressive axial loads. These secondary moments may have a deleterious effect on the strength and stability of the frame and so they must be reckoned with in the analysis and design processes. These are various approaches ranging from very simple to rather rigorous by which a designer can employ to account for these second-order effects. In particular, |
