The columns were subjected to a constant axial load and a pseudo-static lateral load. To monitor the axial deformations of the inner concrete under the cyclic loading, two optic fiber Bragg grating (FBG) strain sensors were pre-embedded in the top of every CFFT and CFST columns. They were arranged parallel to the longitudinal axis of the column and at the two ends of the horizontal axis along the direction of the lateral load. Moreover, each column also included two FBG strain sensors and two electric resistance (ER) strain gauges embedded in the inter-ply of FRP for CFFT or the interface between FRP and steel for CFST, to monitor the hoop deformations of the tube. The embedded sensors made the column have the ability of self-sensing, and the deformations of the column under the combined axial and lateral loads were recorded in real time. The results showed that the lateral loading resistances for the CFFT and CFST columns were much higher than the RC column. Moreover, the composite columns both behaved excellent earthquake resistance ductility and the CFST columns achieved better energy dissipation. Based on the monitoring data, the deteriorations of the composite column at different stages were detected and a seismic damage evaluation method was presented.
