Nell'ambito del Corso di Dottorato in Ingegneria Strutturale, Geotecnica e Rischio Sismico, lunedì 19 febbraio 2024 il Prof. SANTIAGO HUERTA (Universidad Politécnica de Madrid, Spain) terrà un seminario dal titolo: Mechanics of masonry structures: Heyman's approach of equilibrium.

Abstract

Masonry construction was dominant in building and civil engineering until the 19th century. Throughout the 19th century, iron, steel and reinforced concrete gradually displaced the masonry. Consequently, the calculation theories and tools taught today in schools of architecture and engineering refer to the new materials, to structures composed of bars. This theory is inapplicable to a material such as the masonry made of an essentially discontinuous, heterogeneous and anisotropic material which, moreover, can only withstand compression (one-sided material). Professor Heyman has developed modern masonry theory by translating the principles of limit analysis to this structural type. If masonry fulfills certain conditions, the Fundamental Theorems of Limit Analysis are verified. Crucially, the Safe Theorem leads to the "equilibrium approach": that is, we can do safe analysis using only the equations of equilibrium and the material masonry. No assertions need to be made about the boundary conditions, essentially ephemeral and unknowable. The lecture will review the fundamental concepts of Heyman's theory and its application to the analysis of masonry arches and vaults.
