The audience for this reference manual is professional engineers since it describes structural steel materials and their proper assembly. Although this 13th edition of the manual is 15 years out of date, it is an upgrade to my previous 8th edition, because it now includes values for ASD and LRFD design in separate (colored) columns. However, for those who can afford the $400 for the current edition, it would make sense to spend the extra money.
Nice book, accessible price, great, nice and accurate source of information.
It is a very usefully book with a lot of information related on Steel building design. I will recommend such type of books specially for those people who search accurate source of information related with steel building field. Very accessible price.
