Title: Updating the ACI Shear Design Provisions
Author(s): Evan C. Bentz and Michael P. Collins
Publication: Concrete International
Appears on pages(s): 33-38
Keywords: member, stirrups, crack, equation
Abstract:Shear provisions in ACI 318-14 Code have a few disadvantages that could be improved. For example, the provisions can provide overly conservative designs for members heavily loaded in shear and unconservative designs for deep one-way slabs without stirrups. The Code also contains eight separate equations to calculate the nominal shear strength provided by concrete. This article focuses on a method, based on first principles, to simplify shear provisions in the Code and address safety issues.
