A theater seating support assembly comprises a wide-flange beam carrying a concrete slab over metal deck, with a three-quarter-inch gap maintained between components. Cold-formed steel framing consists of 400S162-43 bearing studs at sixteen inches on center, tied into an oversized outer track (400T250-54) secured with 0.157-inch diameter powder-actuated fasteners at each stud to the wide-flange beam, and an inner track (400T150-43) fastened to the studs with number 10 screws while leaving no attachment between the inner and outer tracks. Reinforcing includes number 3 dowels at sixteen inches on center, three continuous number 3 bars, and dowels lapped with slab reinforcement over a specified lap length referencing sheet S003. A kicker is referenced at four feet on center, and notes dictate lateral stud bracing at five-foot maximum spacing along with a minimum one-and-a-half-inch deck bearing at the seating.
