An introduction to six proposals covered in this issue of CI
The goal is to update the one-way shear equations in the ACI 318-19 Code.
ACI is offering a new certification program—Concrete Quality Technical Manager (CQTM).
A method, based on first principles, to simplify shear provisions in the Code and address safety issues.
A presentation of a simplified version of the multi-action shear model developed by the authors.
A unified approach that eliminates limitations of shear design expressions in ACI 318-14 and provides for improved safety.
A proposal that includes an “arch action factor” to simplify and improve on current shear strength calculations.
A proposal for a shear strength model based on the concrete compression zone failure mechanism.
A proposal based on truss models, valid for members with or without shear reinforcement.
