ACI 550.5, 2018 Edition, June 2018 – Code Requirements for the Design of Precast Concrete Diaphragms for Earthquake Motions (ACI 550.5-18) and Commentary (ACI 550.5R-18)
This standard shall apply to precast concrete diaphragms and collectors that are part of the seismic-force-resisting system in structures assigned to SDC C, D, E, or F. It is permissible to use this standard for the design of the same elements in structures assigned to SDC B.
This standard shall apply to precast concrete diaphragms, including a) through c):
a) Diaphragms that consist of a cast-in-place composite topping slab with a thickness of less than 3 in. on precast concrete members
