The slicing technique for the evaluation of the formal efficiency: A comparative study

The paper starts by announcing its goal of comparing the information about the structural analysis of two Napolitan churches. Starting from the structural behaviour of two architectural elements, the ogival arch of the arcade of the Incoronata and the cross vault of S.Eligio, the research aims to provide a wider reflection on the method for assessing the sta-bility of historical architectures in masonry, respectively applied to a two-dimensional and three-dimensional scheme. Therefore, the study of these two Churches is presented with a dis-cussion on the results obtained with regard to the methodology approach to the analysis re-lated to their structural features. The Incoronata Church and S. Eligio are two examples of Angevin architecture in Naples and over the years both them have undergone several transformations that have changed their original appearance. By considering the Viollet Le Duc assumption that “in architecture ge-ometric proportions are established primarily on stability laws, the laws of stability derived from geometry”, the work deals with a study of the form and stability of the system of arches and of the cross vaults to investigate the geometric-configurative nature of the structural ele-ments that constitute gothic architecture.
