Abstract	Application of fiber reinforced polymers (FRPs) for externally bonded reinforcement (EBR) of masonry structures has received extensive attention during the past two decades. However, FRPs are found to be hardly compatible with some structures, especially for historical masonry which exhibiting poor durability and long-term performance. As an alternative, the use of innovative composite materials based on continuous fibers embedded in inorganic matrices (referred to in the literature as Fabric Reinforced Cementitious Matrix (FRCM)) has found recent attention. The typical experimental stress–strain behavior exhibited by a FRCM composite under a monotonic direct tensile test is a tri-linear curve with a first phase that increases linearly according to mortar’s elastic modulus, a second phase which mortar undergoes a multicracking process, and a last phase which the mortar is fully cracked and the composite system behaves almost linearly stiffness of the fabric. This paper presents numerical simulation of the nonlinear tensile behavior of FRCM specimens. In order to study the effect of different type of fiber on the behavior of FRCM specimens, three different type of materials, (1) polyparaphenylene benzobisoxazole (PBO) fiber, (2) high strength steel wire and (3) shape memory alloy (SMA) wire were used for continuous fiber belonging to FRCM specimens. The modeling strategy was initially validated by simulating a monotonic direct tensile test. The adopted modeling strategy was then used to predict the FRCM specimens not only in monotonic loading but also in cyclic tensile loading.
