scope:

ACI 550.4 defines the minimum testing requirements and the acceptance criteria for different performance levels for connections or reinforcement at joints where used to connect precast concrete DT members subject to earthquake loading. Extrapolation of qualification results for connections and reinforcement at joints obtained using ACI 550.4 is not permitted. Project details shall match details qualified using ACI 550.4

Test modules containing discrete connections or reinforcement at joints, tested in accordance with ACI establish dependable and predictable load-deformation responses for those connections or that reinforcement at joints, and can be used to determine the relative deformability category of the connection or reinforcement at joints detailed in accordance with the classification criteria of Chapter 7.
