| Abstract | ||
| In this research the behavior of reactive powder concrete short (RPC) columns with and without reinforcement was reported. Eight specimens of RPC short columns with reinforcing steel and without reinforcing steel are examined and compared with eight specimens of high strength reinforced concrete (HSC) short columns. The columns samples are divided into two groups. The dimensions of the first group are (100 *100* 400) mm and the dimensions of the second group are (70*70*400) mm. The lateral reinforcing steel, which are used in the reinforced concrete short columns, that are tied or spirally reinforced. Experimental data for strength, lateral and axial deformation, ductility and the failure mode were obtained for each test. The failure load of RPC short columns without reinforcing steel is more than the failure load of RPC short columns with reinforcing steel by about 1.222 time for the two groups. The failure mode of RPC short columns without reinforcing steel is shear failure, while the failure mode of RPC short columns with reinforcing steel is rupture of some ties. The carrying capacity of RPC columns with and without reinforcing steel as compared to corresponding HSC columns is about 3.6 and 4.4 times respectively | ||
