SHEAR STRENGTH OF REINFORCED AND PRESTRESSED CONCRETE BEAMS--CEB APPROACH

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 bending and shear. It is compatible with the design method for torsion and combined cases of bending, shear and torsion. The method is theoretically based on the plastic analysis of a truss model consisting of two stringers acting as compression and tension chords, stirrups as posts and a continuous concrete compression field acting 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/
