Summary

A finite element non-linear software for the analysis upto collapse of fibre reinforced polymer (FRP) - reinforced masonry arches is presented in this paper.

In the model, mortar joints are reduced to interfaces and obey a softening holonomic multi-linear law, whereas bricks are assumed elastic and meshed with four-noded isoparametric elements. FRP reinforcement strips are modeled by means of truss elements with limited tensile strength, with values of limit resistance evaluated by means of some simplified formulas provided by the Italian code CNR-DT200 for masonry strengthening with fiber materials.

The model is validated against both some recent experimental results available in the literature relating to masonry arches reinforced in various ways and limit analysis predictions.

A good match among all the results is obtained. A final sensitivity analysis on mortar mechanical properties and holonomic law adopted is presented.
