Advanced nonlinear simulations of a masonry viaduct using a macroscale anisotropic model

This paper presents the results of advanced numerical simulations on the 5-span Quebradas viaduct, located in the Douro valley, built at the beginning of the 20 th century.The bridge structure has been analysed by nonlinear dynamic analysis to represent the response up to collapse under earthquake loading.The analyses are performed by adopting a novel macromodelling approach based on a recently developed macroscale anisotropic masonry model with embedded discontinuities.
