| Abstract | ||
| Experimental investigations were made to determine the ultimate capacity of tied reinforced normal strength concrete columns subjected to both axial and transverse loads. Of the twelve specimens of 1200mm long and 200x200mm cross section tested, six were without steel fiber inclusions. All the specimens were tested under cyclic load until failure with the presence of constant axial load. Specimens differed in the amount of lateral reinforcement. The effects of 1% fiber inclusion by volume and amount of lateral reinforcement were investigated. The test results showed a direct relationship between absorbed energy and the spacing of lateral reinforcement. The ductility of the member increased due to 1% fiber inclusion by about 20-35 %. | ||
