Özet

This paper presents an evaluation on the minimum shear reinforcement requirements given in the ACI, Canadian, and Turkish codes for high-strength concrete. Thirteen beams having the minimum shear reinforcement required by ACI 318-83, the Turkish Code, and the equations proposed in this paper were tested. Concrete strength varied between 60 and 80 MPa (8700 and 11,600 psi). For high-strength concrete (f′c > 69 MPa), the minimum shear reinforcement requirements of the Turkish Code and ACI 318-95 are not very different from one another. Similarly, requirements of the 1994 Canadian Code (CSA A23.3-94) are not too different from the proposed equation. In light of the test results, the adequacy of code requirements are discussed. Emphasis is given to reserve strength, ductility, and cracking.
