Besides a "Standard Method" derived from semi-empirical considerations the new CEB model code proposes a "Refined Method" for the design of reinforced and prestressed concrete members subjected to torsion. It is compatible with the design method for bending and shear and combined cases of bending, shear and torsion. The method is theoretically based on the plastic analysis of a space truss model consisting of stringers acting as compression or tension chords, stirrups as posts and an effective concrete shell forming a compression field at a variable inclination alpha. The model is explained and the design formulas for the "Refined Method" are derived. Comparisons with appropriate test results as well as with the CEB "Standard Method" are made. /Author/
