Abstract
The objective of this research project is to conduct an experimental study of the behavior of carbon fiber-reinforced polymer (CFRP) materials for strengthening reinforced concrete structures. The test program consisted of 23 reinforced concrete columns strengthened with CFRP sheets under static eccentric compressive loading. It is shown that under large eccentric compression loading, ultimate capacity of the columns can be effectively increased with the longitudinal CFRP sheets, and the ductility factors of the columns can be increased with the transverse CFRP sheets. It was observed that the material strength utilization of transverse CFRP sheets was more sufficient than that of longitudinal CFRP.
