Study on Ultimate Bearing Capacity of CFRP-Reinforced Concrete Under Reciprocating Load

Wang, Qi / Yao, Shunzhong

Objective: To study the ultimate bearing capacity of CFRP- reinforced concrete under reciprocating load. Methods: Firstly, a number of CFRP- reinforced concrete specimens were made on the test platform, and the overall compression was adopted to meet the test requirements. Secondly, the load-displacement curve of the specimen is drawn to determine the displacement change of the compression limit state. Finally, the load-deformation situation is analyzed, and the compressive ultimate bearing capacity of the specimen at each position is analyzed to determine the compressive ultimate bearing capacity of the specimen. Results: The compression state of CFRP-reinforced concrete can not be changed by winding CFRP and changing the strength of steel tube. The smaller the overall deformation, the higher the ultimate bearing capacity of CFRP-reinforced concrete. Conclusion: The ultimate compressive bearing capacity of CFRP-reinforced concrete is related to the slenderness ratio, the number of CFRP layers and the circumferential fiber yarn, which plays an important role in improving the strength of CFRP-reinforced concrete.
