Complete with supplement published by Dunod. Traité de charpente written by Emy, a colonel in the engineering corps and former Commandant of the École d'artillerie et du génie de Metz. He took part in Napoleon's campaigns and contributed his knowledge in two fields. Firstly, fortification, for use by engineering students, in which he dealt with the sizing of defensive works, taking into account the environment, topography and armament. Then - and this is the subject of this treatise - carpentry and the improvement of long-span structures. A worthy successor to Philibert de l'Orme, his process enabled the construction of buildings with spans of up to 15 meters - an immense innovation. In this respect, he is considered the inventor of glued laminated timber, since while studying the Wiebeking bridge built at Bemberg, Emy evaluated the possibility of introducing albumin glue between thin wooden plates to reinforce the strength of the arches. This remarkably well-documented work follows the entire timber preparation process, from the roughing and trimming of logs to their transport, the erection of scaffolding and, of course, all the construction elements - timber framing and flooring. But it also takes a historical and encyclopedic approach to carpentry, bringing together examples from many different periods and building traditions. Particularly noteworthy is the work illustrating the maintenance of caissons made by sculptors, perched on complex mobile scaffolding.
