NEW | Floor Bay Comparison Tool – With Vibration
SJI’s design tool helps the SER compare weights, costs, and floor depths for selected bay sizes and framing setups. It offers composite and non-composite designs for open web steel joists, wide flange beams, and girders, though only non-composite joist girders are currently available.
