Abstract

The Textile Reinforced Mortar strengthening systems (TRM) seems to be one of the better solutions to reinforce the historical masonry structures. The study of the testing methods more appropriates to define the mechanical design parameters is actually of main interest for scientific community. The experimental research presented herein was carried out to define the effective bond length of a Basalt_TRM system applied to a homogeneous substrate. The use of the Digital Image Correlation (DIC) based on a cross correlation function has permitted to define the displacement and strain fields and to better describe the debonding phenomena recorded during the tests.
