The future of steel calcs. will really be LRFD. This is similar to WSD and
Strength Design in concrete. Most engineers are using Strength design but
there are still few old engineers who are using WSD. This is because they
are familiar with it and feel more comfortable in using it. Eventually when
all those old engineers are gone then what if left are Strength Designers.
This will be the same as the ASD and LRFD. New engineers are forced to learn
ASD because that is what their Senior Engineers are using. When they become
Sr. Engineers, they won't have any qualms if their new engineers will be
using LRFD because they are already familiar with it. But what is the fuss
of not using LRFD anyway? With the advent of computers, you don't gain much
time in using either ASD or LRFD. You might be saving a little in the
materials but you will be sacrificing quality and strength. Let the design
of steel evolve and let the steel designers use what they feel more
