International Journal of Masonry Research and Innovation (IJMRI), Vol. 9, No. 4, 2024

Abstract: The evolution of the probability density function for some parameters of interest, during the motion of a masonry arch under seismic actions, is determined by solving a first-order partial differential equation. The arch is represented as a one-dimensional structure and is examined in both the unreinforced and fibre-reinforced configurations. In both cases, the influence of the uncertainties of Young's modulus and of the viscous damping coefficient on some displacements and on the amplitude of the cracked regions is determined. Among other things, the results show the potentialities of the method for investigating the effectiveness of FRP-retrofitting to improve the arches' seismic performance.
