Summary

Description	English: Transverse section of Notre-Dame de Paris before the 2019 fire. Timber framework in red, masonry in blues, metal in grey. Center, nave, covered by masonry vault and 55-degree triangular roof (spire shown above and behind). Flanking the nave, side aisles, triforium aisle above, flying buttresses. Note that the vaults thrust outwards on the walls, and the flying buttresses thrust inwards; unless these two forces balance, the wall will be pushed over. Black arrows show the force of the weight of the structure being transmitted to the ground; green arrows show the upwards force of the ground supporting the structure. Orange arrows show the forces in the wood of the roof trusses. Roof trusses cancel out their outwards forces using internal tension (masonry cannot support tension). Light added for clarity.

Source	Own work, derived as indicated under "authors"
Author	Own work, traced from public domain File:Notre Dame 531 transverse crop rot.jpg and heavily altered, mostly using the public domain architectural drawings of Eugène Viollet-le-Duc (see particularly Category:Frame of Notre-Dame de Paris). Photos were also used to verify details; thanks to all Commons contributors who took unconventional shots.

Please note that this is not a finite element analysis, nor yet an architectural drawing; it's an infographic. That said, corrections are welcome. There are probably errors; I honestly have no good data on the space between the the vaults and the floors, for instance. I've made guesses, which I hope are sensible ones. The crypt and foundations are not shows due to lack of data.
