The Portland Cement Association (PCA) has long been the gold standard for providing practical commentary and design aids for the American Concrete Institute’s (ACI) Building Code Requirements. With the release of , the industry saw its first major update in years that included significant changes to shear strength equations, seismic detailing, and high-strength reinforcement.
