“…The shear modulus, G, was calculated as G= cr / cr , where cr is the diagonal cracking strength and cr is the corresponding shear strain. The diagonal cracking strength was defined as cr = max , for the control (unretrofitted) specimens and as cr =0.7 max , for the retrofitted ones, consistent with a number of studies, including the recent ones of Dizhur et al (2013), Parisi et al (2013) and Babaeidarabad et al (2014).…”

Abstract:The present paper proposes an analytical approach for modeling the behavior of textilereinforced mortar (TRM)-strengthened masonry-infilled reinforced concrete (RC) frames under seismic loading. The model falls into the discrete diagonal-element type and is based on the use of single-strut and single-tie elements to represent the infill panel. It builds on the results of past experimental studies by the authors in which the application of TRM jacketing was proved to be effective for the seismic retrofitting of masonry infilled RC frames. The model is implemented in the non-linear finite element code Opensees, with the parameters of the diagonal elements being determined from a series of tests on TRM coupons and masonry specimens. Finally, the results of the numerical analyses are compared with the experimental data of cyclic tests on three-story masonry infilled RC frames, as-build and after retrofitting.It is shown that the model developed herein adequately accounts for the TRM-strengthening contribution to the global response of masonry infilled frames.

“…The tests include those of Prota et al [7], Balsamo et al [10] and Parisi et al [9] along with five tests on uncoursed stone masonry panels. The latter were strengthened on both sides with lime-based mortar and FRP grids (two using basalt grids, BFRP, and other two using glass grid, GFRP; one specimen was tested as built).…”

“…Parisi et al [9] carried out an experimental campaign aimed at assessing the effectiveness of an inorganic matrixgrid (IMG) strengthening system to improve shear behavior of tuff masonry. The system comprised a two-component inorganic glass fiber-reinforced matrix made of hydraulic lime and sand and mixed with latex and water and a balanced bi-directional (0°/90°) polymer-coated AR-glass fiber net.…”

The mechanical behavior of carbon fiber‐reinforced polymer (CFRP) fabric‐reinforced cementitious matrix (FRCM) overlay on clay brick masonry was characterized by means of double‐shear bond, tensile, and out‐of‐plane tests. Different bond lengths in the range 55‐250 mm were analyzed during the double‐shear bond tests. The failure mechanism was slippage of the CFRM mesh, with peak stresses in the fabric around 500 N/mm2 per 100 mm bond length. Tensile tests were performed following AC434.13 with FRCM coupons of 10 and 15 mm thickness, where the mechanical behavior was divided into three stages. The four‐point bending experiments on FRCM‐reinforced prisms showed that the CFRP mesh provided significant added value in both moment capacity (>110%) and deformation capacity (>2800%), when compared to specimens reinforced with solely a cementitious matrix. Additionally, no significant difference was observed between the envelope of the cyclically tested specimen and the statically loaded specimens. A model was proposed where, in contrast to existing design models, the influence of the cementitious matrix layer also was considered. Using the modified tensile test results as input parameters for the model, a good estimation of the experimental results was obtained.
