The family YMCA including 6500 square feet Airnasium, consists of wide flange beams, open web steel joists, and bowed-bottom chord open web steel joists, creating an open, inspiring space at low cost with an accelerated schedule. The framing consists of curved bottom chord open web steel joists, which support the roof deck as well as wide flange beams via a web connection at mid-span. This structural system reduced cost due to the use of special configuration open web joists, which lowered cost compared to conventional alternatives.
