| Abstract | ||
| This paper presents the results of experimental studies on reinforced concrete columns strengthened with carbon fiber reinforced polymer (CFRP) under the combination of axial load and bending moment. A total of twelve specimens with square cross section (120 mm×120mm) were prepared and tested under eccentric compressive loading up to failure. The overall length of specimens with two haunched heads was 1230 mm. Test parameters were the type of concrete material(Normal and Self-compacting), thickness of layer (CFRP)and the load eccentricity, (eccentricity/ column depth ratio of 0.5 and 1). All specimens are Prepared and tested under eccentric compressive loading up to failure. The effects of these parameters on load-displacement and moment-curvature behaviors of the columns as well as the variation of longitudinal strain on different faces of the columns were studied. The results of the study demonstrated a significant enhancement on the performance of strengthened columns compared to unstrengthened columns. | ||
