Independent of the jacket thickness, the measured maximum
transverse strains of CFRP jackets for LSR and NSR specimens
were between 0.007–0.018 and 0.012–0.015, respectively. The
average values of measured transverse strains were about 80–93%
of the value given by the manufacturer. The average values of
measured transverse strains for square, rectangular, and circular
cross sections were about 88, 83, and 79% of the value given by
the manufacturer, respectively
