Textile reinforced ultra-high performance concrete (TR-UHPC) with carbon textile and steel fiber was prepared. The tension stiffening behavior of TR-UHPC and synergistic effects of textile and short fibers were investigated by means of experimental and numerical studies on the mechanical characteristics of textile, UHPC, interfacial bonding and TR-UHPC composites. The prepared TR-UHPC exhibits a pronounced strain-hardening behavior with multiple cracking. The tensile strength, post-crack stiffness and ductility are apparently improved. The tensile behavior of TR-UHPC is mainly affected by the bridging mechanism of steel fibers as the volume fraction of steel fiber is increased from 0.5% to 1.5%. The bonding characteristics between textile and UHPC governs as the fiber volume fraction further increases to 2.0%. The numerical model incorporates the primary mechanisms including tensile properties of textile, stress-crack width relationship of UHPC and interfacial bonding between textile and UHPC. It is indicated that the simulated data by the model are in reasonable agreement with the experimental results.
