Abstract

Strengthening is a valid measure for improving the mechanical performance of unreinforced masonry (URM) structures. Fabric-reinforced cementitious matrix (FRCM) is effectively compatible with masonry materials due to the use of an inorganic matrix. Therefore, FRCM boasts extensive application prospects in strengthening URM structures. Nevertheless, further research still needs to be conducted on the compressive performance of FRCM-confined masonry columns. In this paper, the uniaxial compressive test results of seventy-five FRCM-confined masonry columns were collected from the available literature. Two existing prediction models of the compressive strength of FRCM-confined masonry columns were adopted, and a model was also proposed based on the regression analysis of the collected data. The prediction accuracies of the three models were compared and analyzed, and the characteristic values of the compressive strength of FRCM-confined masonry columns were further obtained via a probabilistic method. These research results can be used to guide the compressive strength design of FRCM-confined masonry columns.
