Abstract
Provided is a CFRP active-passive-confined compression-cast RC column incorporating cathodic protection, which includes a CFRP pipe; multiple longitudinal reinforcements inside the CFRP pipe; a stirrup inside the CFRP pipe connected to the longitudinal reinforcements; compression-cast concrete arranged in the CFRP pipe, the multiple longitudinal reinforcements and the stirrup are embedded in the compression-cast concrete; a power supply having a positive electrode connected to the CFRP pipe and a negative electrode connected to the multiple longitudinal reinforcements. The CFRP pipe with a present thickness forms an active confinement on the compression-cast concrete, and the power supply applies a current to the CFRP pipe as an anode to enable the multiple longitudinal reinforcements to obtain electrons, thus stably protecting the multiple longitudinal reinforcements as a cathode.
