A new predictive model for FRCM-confined columns: A reflection on the composite behavior at peak stress

•The mortar cracks just before, at, or just after the peak stress.•The majority of the studies in the literature focused on small columns.•The relationship fcc/fco versus flu/fco might not be linear and dependent on the type of fiber.•There was large variability in the testing rate used in the literature.•A mechanics-based predictive model was proposed. Fiber-reinforced cementitious matrix (FRCM) composites have become increasingly popular in the last decade, due to the ability of this type of composites to overcome some of the drawbacks related to the use of resin-based composites. Recent studies demonstrate that the application of FRCM composites improves the compressive behavior of confined concrete and masonry columns as well as their ductility. This paper compiles the available experimental data on concrete and masonry columns confined with FRCM composites. A critical review of the experimental data on FRCM-confined columns is carried out to understand which parameters influence the response of the columns. Then, a new predictive model is proposed that takes into account the database available and the mechanics of the confinement.
