Notes:a1. “S” represents the square section shape concrete. “O” represents the octagon section shape concrete. “C” represents the circle section shape concrete. “E” represents the ellipse section shape concrete.b2. Taking “C-2-1-1” as an example, the letter “C” denotes the circle section shape concrete. the number “2” is the layer of CC, the number “1” is the layer of CFRP, and the last number “1” represents the nominal same sample.
