The purpose of the paper produced is to statically test and evaluate the instability of an existing cycle/pedestrian walkway on the Vettabbia agricultural canal, in the province of Milan. In the preliminary analysis part, we reasoned on how to schematize the entire structure, essential for the subsequent analysis. Therefore, through the consultation of the "Update of the «Technical Standards for Construction»" (Ministerial Decree 17 January 2018) and the Ministerial Circular of 21 January 2019, it was possible to get the values of the loads to which the walkway should be subjected, obtaining, through the Ftool calculation software, the stress diagrams. From the diagrams it was possible to identify the most critical sections which were then statically verified with the Von Mises criterion. Finally, the instability was evaluated on the walking surface of the walkway with the Euler criterion.
Il fine dell’elaborato prodotto è quello di verificare staticamente e valutare l’instabilità di una passerella ciclopedonale esistente sul canale agricolo Vettabbia, in provincia di Milano. Nella parte di analisi preliminare si è ragionato su come schematizzare l’intera struttura, essenziale per la successiva analisi. Successivamente, tramite la consultazione del “Aggiornamento delle «Norme Tecniche per le Costruzioni»” (D.M. 17 Gennaio 2018) e della Circolare Ministeriale del 21 Gennaio 2019, si sono potuti ricavare i valori dei carichi a cui assoggettare la passerella, ottenendo, tramite il software di calcolo Ftool, i diagrammi della sollecitazione. Dai diagrammi si sono potute individuare le sezioni più critiche che sono state poi verificate staticamente con il criterio di Von Mises. Infine, l’instabilità è stata valutata sul piano di calpestio della passerella con il criterio di Eulero.

Abstract
The purpose of the paper produced is to statically test and evaluate the instability of an existing cycle/pedestrian walkway on the Vettabbia agricultural canal, in the province of Milan. In the preliminary analysis part, we reasoned on how to schematize the entire structure, essential for the subsequent analysis. Therefore, through the consultation of the "Update of the «Technical Standards for Construction»" (Ministerial Decree 17 January 2018) and the Ministerial Circular of 21 January 2019, it was possible to get the values of the loads to which the walkway should be subjected, obtaining, through the Ftool calculation software, the stress diagrams. From the diagrams it was possible to identify the most critical sections which were then statically verified with the Von Mises criterion. Finally, the instability was evaluated on the walking surface of the walkway with the Euler criterion.| File | Dimensione | Formato | |
