Title: Revisiting the ACI 318 Unified Design Provisions for Flexure and Axial Load
Author(s): Charles W. Dolan
Publication: Concrete International
Appears on pages(s): 33-39
Keywords: beam, slab, high strength, tensile strain
Abstract:The 2014 ACI 318 Building Code has inconsistencies if a slab or beam design is attempted between net tensile strains of 0.004 and 0.005. These inconsistencies become more pressing as designers increasingly specify higher strength concrete and reinforcement. The article discusses issues related to design with a specified concrete strength in excess of 8000 psi (55 MPa) and reinforcement yield strength in excess of 60 ksi (Grade 60 bars, 420 MPa) and lists items in the Code that are being considered for revision.
