Abstract


Concrete structures using carbon fiber constraints , compared to significantly improve components of the bearing capacity and seismic performance , at the same time carbon fiber also has good mechanical and electrical characteristics , that is closely related to the degree of carbon fiber resistance changes with the carbon fiber itself fractured , resistance by monitoring carbon fiber changes directly reflect the characteristics of the force of the carbon fiber material . Confined concrete member of the carbon fiber , not only can take advantage of its superior mechanical properties to improve the bearing capacity and seismic performance of the member , can also use the power of the electrical characteristics of carbon fibers by measuring the change in resistance to monitor the degree of damage of concrete and component damage location , to form carbon fiber damage self-monitoring function constraints astute high strength concrete . Based carbon fiber good electrical characteristics of mechanical performance and force to complete the following tasks : (1) constrained by carbon fiber high - strength concrete prism body test pieces of the repeated load test , study of the stress-strain curve relationship , comparison of repeated load package track stress-strain relationship in the role of line with monotonous load plus uninstall curve rule ; (2) carbon fiber resistance monitoring results , analysis of the characteristics of the carbon fiber by force , explore the restraining stress along the week to the distribution characteristics of the repeated load resistance change rate and lateral strain of the relationship , qualitative description of the inside of concrete degree of injury and destruction of position ; (3) through injury constraints of the carbon fiber high-strength concrete columns of the pseudo- static test , study the damage after the column seismic performance and carbon fiber monitoring results reveal confined high strength carbon fiber concrete cylinders after the earthquake, the energy consumption performance and the extent of the damage , the carbon fiber resistance change rate and transverse strain correspondence between the theoretical basis for the seismic performance of concrete columns confined high strength carbon fiber in the study after the earthquake .
