Title: Shear Strength of Reinforced Concrete Members Subject to High Axial Compressive Stress
Author(s): Alan H. Mattock and Zuhua Wang
Publication: Journal Proceedings
Appears on pages(s): 287-298
Keywords: axial loads; building codes, compressive strength; cracking (fracturing);
diagonal tension; reinforced concrete; shear strength.
Abstract:A comparison is made between the shear strengths calculated according to the ACI Building Code (ACI 318- 77) along with proposals lnade b y AC1 Committee 426, Shear and Diagonal Tension, and shear stengths determined in tests of 38 reinforced concrete members subjected to axial compressive stresses of up to 0.7 f'. The methods of calculation of strength were found to be conservative for all the members tested; and very conservative in’ some cases. Modifications to the ACI Building Code procedures for the shear design of members subject to axial force are proposed to reduce unnecessary conservatism and to safeguard against shear failure primarily due to inclined compression failure of the web concrete.
