Damage propagation in a masonry arch subjected toslow cyclic and dynamic loadings
Journal Title: Frattura ed Integrità Strutturale - Year 2014, Vol 8, Issue 29
Abstract
In the present work, the damage propagation of a masonry arch induced by slow cyclic anddynamic loadings is studied. A two-dimensional model of the arch is proposed. A nonlocal damage-plasticconstitutive law is adopted to reproduce the hysteretic characteristics of the masonry material, subjected tocyclic static loadings or to harmonic dynamic excitations. In particular, the adopted cohesive model is able totake into account different softening laws in tension and in compression, plastic strains, stiffness recovery andloss due to crack closure and reopening. The latter effect is an unavoidable feature for realistically reproducinghysteretic cycles. In the studied case, an inverse procedure is used to calibrate the model parameters. Then,nonlinear static and dynamic responses of the masonry arch are described together with damage propagationpaths.
