Subject: A Practical P-Delta Analysis for FR and PR Frames
| DISCUSSION A Practical P-Delta Analysis Method for Type FR and PR Frames Paper by E. M. LUI (3rd Quarter, 1989) Discussion by Phillip S. Carskaddan the engineer who has never been totally comfortable with the destabilizing effects of compressive forces on an elastic frame, this paper is just the ticket. Starting with the well-known differential equation of a beam-column, Lui deftly moves away from the calculus by a subtle algebraic redefinition of terms that reduces the problem to a traditional first-order structural analysis problem. Requiring at most a few iterations, it basically makes the |
