A One-Dimensional Evolutionary Masonry Model with Low Tensile Strength

In the paper a low tension (LT) elastic-brittle mechanical model for use in the study of structures made of masonry material is discussed. With respect to the NT hypothesis, the model is able to reproduce results in major agreement with the real behaviour of the masonry, since it is able to embed even a low tensile resistance capacity of the material. The LT solution is investigated in order explore its relationship with the other models that are usually adopted in common practice.
