RE: k's in LRFD Third Edition

[Subject Prev][Subject Next][Thread Prev][Thread Next]
They do mean different things.  IIRC, the decimal number is for calculations and the fractional number is for detailing (clearances etc).  To be conservative, you need different numbers for different conditions.  Remember the numbers in the tables are averages from the many mills in the industry.

Subject: k's in LRFD Third Edition

This is probably a stupid question, but what is the difference in the "k's" that are given for wide flange beams in the LRFD third edition.  If I look at a W24x68, I see a k of 1.09 in one column and 1 1/2 in another.  Is this an error or do they mean different things?
Thanks in advance,
