| Popis: | In this paper, the structural response of a segmental dry-joint masonry arch subjected to increasing support displacements was investigated. The arch behaviour was analysed in the framework of large displacements using finite element (FE) and rigid block (RB) models, both based on a micro-modelling strategy. Once the two modelling approaches were validated against experimental results from literature, nonlinear analyses were carried out considering different configurations of support displacements (i.e. vertical, horizontal and inclined). The effect of the displacement direction on the arch response was evaluated in terms of initial hinge position, collapse mechanism, support reaction-displacements curves as well as ultimate displacement capacity. The sensitivity of the results to the number of voussoirs was also investigated. The good agreement between the results from the two models allowed to draw new conclusions about the response of segmental masonry arches to inclined support displacements in the large displacement regime. A limit displacement domain computed as a function of the direction of the support displacements is also proposed. The financial support of PRIN 2015 Program by the Italian Ministry of Education, University and Research (MIUR) is gratefully acknowledged for funding the research project “Protecting the Cultural Heritage from water-soil interaction related threats” (Prot.
