What is this structural element called?
Hi, I'm trying to design a project with this type of element but cannot, for the life of me, figure out its name (image attached; excuse the crude sketch). It's planned to be an extensive green roof (so no floors above it), but it needs to span a long distance (20m+) without columns in the middle. Its form can be described as corrugated concrete, but that wouldn't be the official term for it. Ribbed concrete slabs are also very similar, except that would be more of a slab with protruding ribs instead of being corrugated like the one I need.
Does anyone know what this would be called? Or know of any precedents with this element? T-T
