Description
Summary:In the present paper, a finite element methodology for the static and dynamic nonlinear analysis of concrete and large order historical masonry structures is described and applied to the seismic analysis of the historic Arta bridge, in western Greece, under 2D and 3D conditions. According to this methodology, the inelastic material behaviour is simulated with the aid of the theory of continuum damage mechanics. More specifically, the developed damage model is a combination of the theories of Mazars and Faria-Oliver and is characterized by its successful modeling of the mechanical behaviour when applied to concrete or masonry structures. In addition, the model permits an easy calculation of damage indices for various locations of a structure and a global (qualitative) damage index for the whole structure as well. T
