Structural verifications according to ACI 318-19

3D CSFM is in accordance with ACI 318-19, chapter 6.8.1.1. In order for the 3D CSFM to meet the requirements from ACI 318-19 Section 6.8.1.2, a lot of verification testing was done at various universities. Individual articles summarizing the results of verification and validation can be found at the following link.
