Abstract: |
Shear Design of Members with Circular Sections Reinforced by Stirrups or SpiralsFor RC members with circular sections the stresses within stirrups or spiral reinforcements as well as within the inclined compression field are derived from the specific inner shear flow and elaborated to gain equations for the shear resistances. The equations use the established scheme of DIN 1045-1 or EC 2 extended by an efficiency factor reducing resistances compared to rectangular sections to about 75%. Alternatively, an additive approach for the resistance of the tensile strut is proposed. It sums up from concrete contributions, strut-and-tie actions as well as arch contributions introduced by axial forces. Both approaches are verified to experimental data taken from extensive test series. The characteristics of stirrup stresses and stirrup activation as well as effects from the shear reinforcement ratio, the use of inclined spirals and axial forces are presented. |
