| 要旨 | Three-dimensional finite element analysis, which incorporating three-dimensional elasto-plastic and continuum fracture model, was utilized to study the effect of strain gradient on confinement of reinforced concrete columns. Section capacity was calculated based on stress-strain relationship for each local fiber in concrete section. For section with strain gradient, the capacity of reinforced concrete section increases significantly for the case of higher axial load, while ductility increases for lower axial load. |
