Abstract: The present study is an attempt to analyze the flexural behavior of mesh and fiber rein-forced cementitious composites. For this purpose, four-point bending tests were conducted on slabs (700 mm × 200 mm × 25 mm thick) with hybrid reinforcing mix combinations of steel mesh (SM - 3, 4, 5 layers) and stainless steel (SS) fibers (0-2.5% of volume of specimens, with 0.5% interval). Higher performance is seen in hybrid steel mesh and stainless steel fiber reinforced cementitious composites (HSMSSFRCC) compared to Steel Mesh Reinforced Cementitious Composites (SMRCC). Strain-hardening behavior of HSMSSFRCC was evidenced by multiple cracking behavior with excellent crack distribution. The crack width was found to reduce on increase in mesh layers and fiber percentage. Also, the crack spacing in the moment region was found to decrease on increase in reinforcement volume fraction. Statistical regression models were developed for predicting the flexural strength of SMRCC and HSMSSFRCC.
