Abstract:
This paper details an experimental investigation of the shear of high-strength plain concrete specimens [ fc' 9000 to 500 psi (62 to 86 MPa)] with a shear span ratio of I and under ax-compressive stresses of up to 0.62 fc' . The ratio of condensed mi croilica fume to cement was 0.37. The experimental data were ked against the shear strength calculated according to the ACI building Code (ACI 318-83) and the proposals made by ACI-ASCE Committee 426 on Shear and Diagonal Tension. The theoretical shear strength of concrete V, increases with respect to both the compressive of concrete fc' and the axial compressive stress N,/A,. The es in the calculated shear strength were found to be conservaal with regard to the increase, but unconservative with respect the increase in N/A,.
