Good morning.
I have a project currently under construction and received elevator shop drawings for review. I had provided an single elevator hoist beam over two (2) elevator shafts with two (2) hoist loads simultaneously on the hoist beam on the design drawings. However, the elevator shop...

Working on a job in South Carolina to determine capacities of existing joists. Most I have had to measure and search the historical SJI tables.
But, for one gymnasium we have drawings that specify a 60G22 steel joist for the roof framing. The span is approximately 101'-0". They are spaced at...
