The Use of Rational Design Methods for Shear

The essential features of the "modified compression field theory" are described. A group of behavioral models, based on these assumptions is presented. The use of these models is illustrated and reference is made to experimental data and to existing design codes. A simple, unified design method for shear, that is able to approach both routine and "unusual design problems," is presented. The method is applicable to both prestressed and non-prestressed concrete members; it treats members subjected to either axial tension or axial compression, and it treats both members with web reinforcement and members without web reinforcement.
