–Rebar congestion caused by many layers of conventional hoops and crossties

Conventional Column/Beam Connection
Conventional Confinement Reinforcement Problems

hoops and crossties which inhibit the flow of concrete during placement.Also, the many seismic hooks not only impede
the concrete flow but also obstruct the movement of the vibrating compactor.
