HOW TO USE
THIS BOOK
The formulas presented in this book are intended for use by civil engineers
in every aspect of their professional work—design, evaluation, construction,
repair, etc.
To find a suitable formula for the situation you face, start by consulting the
index. Every effort has been made to present a comprehensive listing of all for-
mulas in the book.
Once you find the formula you seek, read any accompanying text giving back-
ground information about the formula. Then when you understand the formula
and its applications, insert the numerical values for the variables in the formula.
Solve the formula and use the results for the task at hand.
Where a formula may come from a regulatory code, or where a code exists
for the particular work being done, be certain to check the latest edition of the
applicable code to see that the given formula agrees with the code formula. If it
does not agree, be certain to use the latest code formula available. Remember,
as a design engineer you are responsible for the structures you plan, design, and
build. Using the latest edition of any governing code is the only sensible way to
produce a safe and dependable design that you will be proud to be associated
with. Further, you will sleep more peacefully!
