Abstract
Since the beginning of the structural analysis of masonry structures, it has been sought to know their behavior taking into account the influence of the different elements that make it up, evolving the structural analysis of masonry arches to analyze the fracto-mechanical behavior of the masonry. This article presents the adaptation of the Tsai-Hill failure criterion for orthotropic materials, for the study of masonry arches. Implementing the adaptation in a VUSFLD subroutine of ABAQUS in Fortran programming language. This subroutine has been validated in view of the failure of the mortar, and the effect of considering mortar in the analysis of a masonry arch. The subroutine implemented in a masomodel allows observing its contribution to the bearing capacity of an arch. Key Words: Masonry Arch; ABAQUS subroutine; failure Criterion; Mortar; structural analysis; Tsai-Hill failure criterion
