Abstract:
Currently, there is no established standard for hybrid construction joints. The upcoming ACI PRC-360, “Design of Slabs-on Ground,” will provide information on the purpose and design of such joints. However, the document will not provide a solitary standard hybrid joint detail, as the design depends on the amount of reinforcement used throughout the slab and the type of dowels specified for the construction joints.
