WHY PLASTIC DESIGN by Lynn S. Beedle ... - Lehigh University

It .is our objective in this conference to present to you the available
methods of plastic analysis, the design procedures that have been worked out
using these methods, the experimental verification of these procedures by actual
test results, and .to cover in the time that permits the secondary design consid­
erations that so often are a stumbling block to any new design technique. In
.short, we hope to stimulate your further study of the topic. -If we do not suc­
ceed in demonstrating the simplicity of the plastic method, please remember that
you didn't master all you know about present design methods in a few one-hour
lectures.
It is the purpose of this particular talk to describe the fundamental
concepts involved in plastic design, to justify its application to structural
steel frames, and to demonstrate that some ·of the concepts are actually a part
of our present design procedures.
To some of you these concepts may be new. Others of you have had
some experience in solving problems. It won't hurt any of us, however,to have
definitions clearly in mind and these are included in an appendix.
