Structural diagnosis of historic timber structures: the Diplomatic Room of the of Royal Palace of Naples

Abstract

The aim of this article is to describe the diagnosis process made on the timber structure that holds up the vault of the Diplomatic Room of the Royal Palace in Naples (Italy). After a brief historical description of the Royal Palace and the Diplomatic Room, it discusses the methodology according to Italian regulations and the speci­fic problems that arose during the works. To complete the diagnosis, a dendrochronological analysis of the wooden elements was performed. The results show the residual mechanical properties of each structural element and the main problems to be resolved by the restorers. The dendrochronological conclusions yield that the dating of the elements is compatible with that of the frescoes on the vault and therefore demonstrate that the elements have not been replaced.
