japanese practice ryuji nakamura & associates has created ‘concrete roof’, an experimental model for a concrete roof structure intended to span 19.14 square meters. supported with three pillars, the monolithic module features a triangulated beam arrangement. a manipulation derived from a two-way slab structure, weight is distributed and directed to vertical supports along their angled paths. formed with plaster, the small scale representation is the size of a table.

  • Shape in plan is quite nice.

  • This is a joke isn’t it?

  • Nice table.

  • I assume it’s the model making technique that’s experimental? Concrete design like that has been around for the best part of 100 years.

    Talking about typical concrete design…. is it only 19.14 square metres?

    Scaling from the 19.14 square metres area, the slab would appear to be approx 200mm thick. I don’t even think the downstand beams are structurally necessary.

    The structure would have some lateral stability issues however.
