“…the number of bending cycles to buckling. It should be noted that the range of wrinkle amplitudes measured on the tubular specimens [Pournara et al (2012), Pappa & Karamanos (2012)] are significantly lower than the corresponding limits specified in EN 10216.…”

“…Furthermore, initial wrinkle measurements have been performed, and the measured wrinkle amplitudes, expressed as a percentage of the tube wall thickness, were found less than 5%, with a representative value equal to about 0.8% [Pournara et al (2012), Pappa & Karamanos (2012)]. Residual stress measurements have also been obtained and indicated very small residual stresses in the longitudinal direction and residual stresses less than 17% of the yield stress in the hoop direction [Pournara et al (2012)]. Given the fact that, in the case of bending loading, the primary stresses are in the longitudinal direction, the small residual stresses in the hoop direction can be neglected for the purposes of the present analysis.…”

“…al., 2012). These high-strength steel tubes have also been Pournara et al (2012) in terms of their structural beam-column behavior. In that work the need for a more reliable classification of highstrength steel CHS sections has been addressed.…”

“…Residual stress measurements have also been performed in both the axial and the circumferential hoop direction (Pournara et al 2012). The measurements in the hoop direction have been obtained through the "splitting ring" method, as specified in ASTM E1928-99, and resulted in an opening deformation (gap) of 17.7 mm, corresponding to a maximum hoop stress of 122 MPa (about 16% of the actual yield stress).…”
