You will probably be disappointed ... I know I was to find out none were included. Even calling the manufacturer does not get you all the information. One manufacturer reluctantly agreed to give me the properties (dimensions only) of any joist that I asked for over the phone. So I have to call every time I need the properties for a different joist and then perform the property calculations. Does anybody know why the properties of joists are not published? My theory is that each joist is rolled specifically for each loading detailed on the drawings and if they can roll the angles 1/32" thinner or shorten the angle legs by a 1/4" and still meet your loading/span criteria, the manufacturer will do it to save material and increase profits. I recall seeing K-joist properties being included in the FloorVib2 program offered by STRUCTURAL ENGINEERS INC., 537 Wisteria Drive, Radford, VA 24141, 540.731.3330, 540.639.0713 FAX. Cost is $250 plus $10 s/h plus VA sales tax if you are a resident. If I do more work with composite joists I would invest in this but right now the price is too steep just to get joist properties. Because once you have the joist properties, you will need the joist girder properties and you are back where you started ... looking for unpublished data. Good luck! William J. Keil, P.E.
