The FastFloor C team has created two building archetypes for the FastFloor C all-steel floor modules. The first is a 4-story braced frame building, and the second is a 40-story building with a shear core. Reports on these two building archetypes have recently been completed and posted to the library repository at Virginia Tech and are available below:

These FastFloor C building archetypes are utilized throughout the FastFloor C research and help to determine appropriate sizes, connections, and other details. The archetype work was conducted at Virginia Tech and Johns Hopkins University as part of the overall FastFloor C effort.
