Interior of the Pantheon dome, found from beneath. The concrete with the coffered dome was laid on moulds, mounted on momentary scaffolding.
In reinforced concrete, the tensile power of steel plus the compressional energy of concrete render a member effective at sustaining hefty stresses of all types above appreciable spans.
