Some states' DOT agencies post their own in-house developed engineering aids such as beam/column splice tables. I think Ohio's DOT is a good one. Their standards are very useful.
One other source that I have found is on the USACE web page. As much as I reference it in this forum, you would think I would be able to include it by now. Try
and search for publications. They have cad details and full cad structural drawings for dormitories and barracks (typical steel, concrete, and masonry work for 2 story buildings). Their drawings are in 'bid' format, which means that you will have to download their cad viewer to view the .CAL files. This is a good start to get a feel for the layout of structural drawings.
