Presentation of Loads to Joist Manufacturer 1

Hello,

I have a project where I designed my main wind force resisting system to utilize 60" deep joist girders and moment connections to the columns. I have referenced the SJI technical digest #11 "Design of Lateral Load Resisting Frames Using Steel Joists and Joist Girders". I am trying to determine the best way to relay my requirements to the joist manufacturer. I have non-uniformly loaded panel points so I think I should use a table like 6-3 of my attachment and that will allow the manufacturer to "appropriately sum the loads per the specified load combinations". If I do, how do I specify my lateral loads from wind? Is a table like 6-3 sufficient for the manufacturer, or do I need to show what the left-end and right-end moments, and what the top and bottom chord forces are for all the applicable load cases like in table 6-2?

Additionally, I know I need to specify a minimum moment of inertia based on what I analyzed, but that's straight-forward to me and I don't have questions about that.

Thanks for any advice!

Call a manufacturer such as Vulcraft and ask how they would like the information presented.

I can confirm. I used to work for a joist manufacturer. We had our own tables that were setup to look like the format we entered into software. We would much prefer people to send it to us the way we like it rather than a generic presentation. Helps minimize errors.
 
Ok, that's what I'll do. Thanks
