Abstract
In this study, the effects of carbon fiber orientations on the strengthening of small-scale thin-walled steel cylinders (TSCs) under axial compression were experimentally and numerically investigated. Besides, the strengthening effects of various types of carbon fiber reinforced polymers (CFRPs) on the load-carrying capacity of full-scale TSCs were numerically investigated. The results showed that circumferential CFRP layers (0°) have significant effects on the increased load-carrying capacity of TSCs under axial compression, whereas, only 90° CFRP layers had small strengthening effects for TSCs under axial compression. When the TSCs subjected to bending shear loads with high values of internal pressures, the appearances of circumferential fibers also brought better strengthening effects than only the angled fibers for TSCs.
