Abstract:
The basic one-way shear provisions in the ACI 318 Building Code have remained unchanged since 1963. However, researchers have developed new methods that better account for the depth of the compression zone, the amount of longitudinal reinforcement, and the size effect on shear capacity. This article introduces a set of six articles that describe proposals being used to develop change proposals for the one-way shear equations for the ACI 318-19 Code. The impetus and activities leading to the change proposals are summarized.
