Raker beams that support the precast risers can be designed using steel or precast concrete. Gravity connections between the precast riser and raker assembly should be designed with field access in consideration. Gravity connection shown allows access to connection via blockouts in riser and connection is completed from above risers. Connections are typically designated to be fixed on one end and allow slip on the other end for seismic design. After connection is completed, foam voids are placed over bolted connection and blockout is grouted solid from top of riser.
Stadia/Arena
Stadium design and the environment the structure creates for the fan experience is often the trademark that defines a city. Architects need stadium framing products that are versatile, supporting their creative designs, and are durable enough to resist heavy loads and foot traffic. Precast stadia is versatile and has been the clear choice for designers who want to create seating configurations of any shape with unobstructed and unique open spaces that enhance the fan experience.
