Abstract

This paper describes an experimental program for improvement of the shear resistance of unreinforced masonry (URM) by plastering with two layers of short polypropylene fibers (fiber length = 12 mm) embedded into a cementitious matrix under in-plane loading. Six diagonal compression tests as of
ASTM E519-02, were carried out on masonry panels of dimensions 1.2 x 1.2 x 0.25 m built and tested at the laboratory. The main mechanical parameters such as the shear strength, modulus of rigidity and ductility were assessed and compared before and after strengthening. Additionally, the panels were also modelled using discrete micro-modelling using DIANA 9.6 and a non-linear analysis was conducted.
The results showed that polypropylene reinforced mortar coating increased the in-plane capacity of the unreinforced masonry by 270%.
