Thrust Line Analysis is a classic problem in structural engineering. This thesis focuses on the analysis of the thrust line in arches and presents a method used for evaluating the safety and stability of such structures. The objective of this research is to apply and develop an efficient numerical procedure for determining the minimum and maximum thrust solutions, considering both vertical and horizontal loads. The proposed algorithm simplifies the equilibrium equations of the system and utilizes a linear optimization approach with constraints, implemented in the MATLAB environment. The code, originally constructed by Francesco Marmo, is extended so that it can be automated as much as possible and can be activated for arcs of different shapes. In the thesis, applications of the code to arched structures such as the Keriti Bridge, the Neoria of Chania, the Kakodiki Bridge and the Stathmashie Bridge are carried out. Parametric analysis using ideal arcs with varying parameters is also included. The results show the accuracy and effectiveness of the algorithm in terms of determining the thrust lines and calculating the maximum vertical and horizontal loads that can be applied to the structures until they are considered unstable.
