ACI 447R-18 PDF Download

ACI 447R-18 is a design guide that focuses on the consideration and accounting of twisting moments in two-way slabs. The guide aims to assist practitioners in understanding the concept of twisting moments in slabs, as well as the methods available for designing with these forces.

The guide provides theoretical and visual descriptions of twisting moments, helping readers visualize and comprehend their effects on slabs. It discusses six different methods that can be used to account for twisting moments in design, allowing designers to choose the most appropriate method for their specific project.

The guide also evaluates the applicability of these methods by comparing the designs resulting from each approach for various types and geometries of two-way slabs. This provides practitioners with a comprehensive understanding of the different options available and their potential outcomes.

It is important to note that the theories and principles described in ACI 447R-18 are also applicable to the design of two-way wall and two-way dome systems, extending the utility of the guide beyond just two-way slabs.
