Masonry elements are often confined in order to improve their structural capacity. Generalized methods to assess the behavior of confined masonry columns are usually derived from concrete confinement models. However, concrete and masonry present several crucial differences due to their physical and mechanical properties. The recent scientific researches provided relevant information on the experimental behavior of confined masonry columns. In this paper, the Stassi D'Alia failure criterion, recently particularized by the authors to assess the axial capacity of confined solid clay brick masonry, has been discussed remarking its potential as a solid mechanics model. The model has been validated by means of comparisons with 67 relevant experimental results available in the scientific literature. The tested specimens made of solid clay bricks were strengthened with several types of strengthening systems. In order to assess the potential of the confined model, the comparison included also other four available mechanical models based on classical failure criteria available in the scientific literature. The reliability of the confinement models was remarked by assessing some relevant statistical parameters.

“…The experimental dataset of FRP-confined columns is referred to both polygonal [1,3,[8][9][10][11] and circular [12][13][14] cross-section, analogously to the database of FRCM, containing polygonal [15][16][17][18][19][20][21][22][23][24][25][26] and circular [14,27] samples. For both the FRP and FRCM dataset, different values of corner radius are investigated in case of squared and rectangular specimens, namely 0, 10, 20 and 25 mm in the FRP-dataset, while 12, 20 and 30 mm for FRCM-specimens.…”

“…Several experimental results available in the literature are used for validation [1, 3; 8-27], in which clay brick, tuff and calcarenite masonries were confined by glass and basalt fibres with FRP or FRCM systems. The FRP database contains the results of 67 tests on squared and rectangular columns with different corner radius [1,3,[8][9][10][11] and masonry cylinders [12][13][14]. The FRCM database is constituted by the outputs from 81 compressive tests on polygonal [15][16][17][18][19][20][21][22][23][24][25][26] and circular [14,27] columns.…”

This paper presents a critical review of the most established analytical models for the prediction of the compressive strength of FRP and FRCM-confined masonry columns. In particular, two types of fibres are analysed, i.e. glass and basalt. A wide dataset available in the literature is used for the application of the analytical models and for the development of parametric analyses useful for the critical comparison of FRP vs. FRCM confinement technique and glass vs. basalt fibres to be adopted as reinforcement of masonry substrate. The effects of stiffness and strength of the reinforcement, the number of reinforcing layers, the compressive strength of masonry and the cross-section shape are investigated.
