Abstract
Current procedures for estimating effective
length factors for web-tapered members rely
heavily on the use of charts and graphs. This
makes them difficult to implement using a
computer. In addition, they are often based
on unrealistic assumptions. In cases where
these assumptions are not satisfied, design
errors may result. This investigation proposes
a modification to an effective length factor
expression developed by Lui (1992). This
modification allows the expression to be
applied to web-tapered members with good
accuracy.
A derivation of the proposed expression is
presented, and the results obtained by
applying the expression to a range of frames
are compared to the results obtained from
second-order finite element analyses.
Calculations involved in using the expression
are presented.

As a contractor who still does my fair share of carpentry, and who has been pricing myself a shop, I prefer metal. I can get a Metal Building erected (material & labor) for the same price that I would pay for the wood shop, with siding, roofing, etc. I wanted to build it myself but cannot justify the obvious choice. By the way, I price out jobs every week.
