What is Strut-and-Tie Methods Evaluation and Enhancements about?

This article evaluates existing strut-and-tie modeling (STM) design provisions and recommends improvements based on analysis of a database of 905 deep beam shear tests. The authors found that current ACI 318-11 and AASHTO LRFD provisions for deep beam shear design are overly conservative. They propose modifications to these methods to create an improved, transparent STM procedure calibrated by experimental data. The recommended procedure aims to improve accuracy while maintaining conservatism.
