Study on the mechanical property of textile reinforced self-stressing concrete sheets

• Adopts textile reinforced self-stressing concrete (TRSSC) composite materials.
• Pull-out and bending tests of TRSSC sheets to gain better stress distribution of the bond behavior and bending property.
• The calculation formula of the bond strength is established based on Tepfers’ partly cracked thick-walled cylinder model.
• Derivation of calculation models for TRSSC sheets elimination pressure moment.

This study tests the mechanical property of textile reinforced self-stressing concrete (TRSSC) sheets, particularly the bond behavior between fiber bundles and self-stressing concrete sheets and the bending property of a TRSSC one-way sheet under four-point loading to understand the enhancement mechanism associated with TRSSC. Bond test results show that the ultimate pull-out force increases with an increase in the initial bond length. The bond behavior between textiles and self-stressing concrete is superior to that between textiles and common concrete. The calculation formula of bond strength is established, and the bending test results show that the cracking load of the TRSSC sheets is greater than that of textile reinforced concrete (TRC) sheets. The cracking capacity and ultimate bearing capacity of TRSSC is analyzed, and the calculation results are congruent with the experimental results.
