Thrust Line Analysis for Reinforced Arches

The Thrust Line Analysis (TLA) is a methodology that can be employed to identify the position and shape of the thrust line in a masonry arch, providing information on the minimum and maximum thrust solutions that can exist within the arch. This paper presents an enhancement to the TLA that considers the influence of the Fiber-Reinforced Cementitious Matrix (FRCM) composite system. The numerical examples presented in this paper show that the proposed extension to the TLA can accurately forecast the behaviour of reinforced masonry arches and can offer valuable perspectives into the design and evaluation of such structures.
