Abstract

To study the impact resistance of the stainless steel reinforced concrete after reinforced with CFRP (Carbon Fibre Reinforced Plastic), the multifunction ultra-high heavy drop hammer test system was adopted to conduct multiple horizontal impact test research on three stainless steel reinforced concrete piers before and after they are reinforced. The test results showed that with equal impact energy, the maximum impact force of the stainless steel reinforced concrete piers was larger than that of the stainless steel reinforced concrete piers that were reinforced with CFRP, while after the concrete piers were reinforced, the peak displacement of the piers was obviously smaller than that before they were reinforced and the residual deformation also became smaller, which improved the flexural rigidity of the section. And the local anti-damage capacity can be improved so as to lengthen the life of structures by reinforcing the stainless steel reinforced concrete pier with carbon fiber.
