Progettazione e verifica strutturale di serbatoi circolari in calcestruzzo armato

This master’s thesis in Civil Engineering, with a specialization in Structural Engineering, is based on a two-year professional experience at WolfSystem, an Italian branch specializing in the design of reinforced concrete tanks. The thesis focuses on the structural analysis and design of circular reinforced concrete silos and tanks used in biogas plants and industrial applications. The primary objectives include: an in-depth study of current regulations and scientific literature related to the design and verification of two-dimensional reinforced concrete elements; a comparison between numerical results obtained using industry-standard software (Autodesk Revit and Robot Structural Analysis) and those from COMSOL Multiphysics, which was fully implemented independently; and the development of a clear, reproducible workflow for professionals to validate results using any structural software. Additionally, a parametric model is proposed to streamline and automate the design and verification process for a typical biogas tank, significantly reducing design time and improving technical documentation. The thesis is divided into two main parts: a theoretical section exploring design codes, limit state verifications, and calculation methodologies; and a practical section presenting a structural case study of a buried cylindrical tank, including numerical analysis, resistance checks, and an automated workflow to enhance design efficiency and reliability.

La presente tesi magistrale in Ingegneria Civile, curriculum Strutture, nasce da un’esperienza biennale presso l’azienda WolfSystem e si concentra sulla progettazione e verifica strutturale di serbatoi e silos in calcestruzzo armato destinati a impianti biogas e applicazioni industriali. L’obiettivo principale è analizzare e confrontare le prestazioni di diversi software di calcolo strutturale (Revit, Robot Structural Analysis e Comsol Multiphysics), sviluppando un modello parametrico automatizzato per migliorare efficienza e accuratezza progettuale. La tesi si articola in due parti: una teorica, con approfondimento normativo e metodologico sulle verifiche agli stati limite; l’altra pratica, con analisi numerica e verifiche di resistenza su un caso studio reale.
