: Odone Belluzzi, elastic stability, Euler buckling, Scienza delle Costruzioni, history of structural mechanics. 1. Introduction Odone Belluzzi’s Scienza delle Costruzioni remains one of the most comprehensive treatments of structural mechanics ever written in Italian. Published in multiple volumes between the 1940s and 1950s, it reflects a unique synthesis of rigorous mathematical derivation and practical engineering insight. Chapter 13 of Volume 3 (often referred to as “La stabilità dell’equilibrio elastico: aste compresse”) is particularly significant because it addresses the non-trivial phenomenon of bifurcation of equilibrium — the point at which a perfectly straight, centrally loaded column can suddenly deflect laterally under no increase in load.

(simulated) Department of Structural and Mechanical Engineering, University of Bologna In honor of Odone Belluzzi (1899–1951) Abstract This paper investigates the theoretical and pedagogical legacy of Odone Belluzzi’s treatment of elastic stability in his Scienza delle Costruzioni , focusing on what corresponds to Chapter 13 of the third volume: the buckling of compressed columns. We examine how Belluzzi reconciled Euler’s bifurcation theory with real-world imperfections, material non-linearity, and experimental evidence. The study also traces the epistemological shift from 19th-century deterministic models to Belluzzi’s more nuanced, engineering-oriented approach. Key contributions include his discussion of the transition from stable to unstable equilibrium and his prescient remarks on post-buckling behavior. Finally, we assess the enduring relevance of Belluzzi’s didactic method for modern computational mechanics. Odone Belluzzi Scienza Delle Costruzioni Pdf 13
