Engineer warns Notre-Dame fire-damaged walls could be unstable
Paolo Vannucci, a mechanical engineer at the University of Versailles warns that the walls of the Notre-Dame may be unstable after the fire destroyed the roof and vaults of the monument. He advices to take precautionary measures and reinforce the walls as soon as possible. The structural system of Gothic architecture, with the copious use of ‘thin clustered columns, flying buttresses and counter-supports’ relies on all parts to work in conjunction with each other.
With the collapse of the roof, this interconnected system has been compromised and at times of high speed winds, especially the walls are at risk of tumbling down.
Vannucci warns that this may delay the desired time schedule of five years, mentioned by President Macron.
