| dc.description.abstract | This study presents an assessment of the seismic performance of rectangular concrete columns internally reinforced with G (Glass) FRP. Eight full-scale columns prototypes, with a shear span of 1650-mm and 350-mm square cross-section, were constructed and tested under simulated seismic waves and constant axial loading. These columns simulate the lower portion of first storey columns between the footing and the contra-flexure point. Therefore, heavy steel-RC footing was post-tensioned to the laboratory strong floor in order to provide rational fixity to the column. The test parameters included reinforcement type, longitudinal reinforcement ratio, level of axial load, and stirrup spacing. Test results showed that deformability of GFRP-RC columns prototypes successfully replaced ductility in steel-RC columns in dissipating the seismic energy in the presence of constant axial load. Furthermore, the failure of sections was prominent by flexure concrete crushing at high drifts. Accordingly, GFRP-RC columns are a doable application in earthquake-resistant structures. | en_US |
