Review of Design Procedures for Shear and Torsion in Reinforced and Prestressed Concrete
The object of this study is to propose and evaluate a design procedure for shear and torsion in reinforced and prestressed concrete beams, with the aim of clarifying and simplifying current design provisions and AASHTO standard specifications. This report summarizes an extensive literature review which documents the development of present regulations and procedures. In addition, the report outlines the general background and derivation of a powerful three-dimensional space truss model with variable angle of inclination of the diagonal elements. This conceptual model was developed by European and Canadian engineers over the past 15 years. The model is shown to be a plasticity lower bound solution which matches the upper bound solution. Thus the model is a mathematically valid solution which represents the failure load. Extension of the use of this model into a design procedure is outlined. Experimental verification, detailed design procedures and specifications, and example applications are given in later reports in this series.
