Strength and Ductility of Reinforced Concrete Columns Subjected to Uniaxial Compression |
| Abstract |
This paper is to study the behavior of reinforced concrete columns subjected to uniaxial compression. The main objectives of the experimental investigation are to formulate a more reliable stress-strain relationship for confined concrete in compression and determine the ultimate strength considering the effects of (1) tie spacing (2)volumetric ratio of lateral steel to concrete core, tie configuration. To achieve the above objectives, ten reinforced concrete and two plain concrete speciments were tested. In the theoretical analysis, the analytical model is applied to the specimens and compared with experimental results.As a result, tie steel and support tie steel which confined the core concrete were behaved effectively after the concrete cover started to spall. The amount of lateral steel sppeared to have an effect of the behavior of the confined concrete. |
