Modified Compression Field Theory
ShellDesign has recently been developed to also include MCFT in the design calculations. This method is a consistent model for reinforced concrete in shear. MCFT has been developed at the University of Toronto and is a method capable of predicting the shear response of cracked reinforced and prestressed concrete. MCFT will, in addition to providing a more correct answer, give engineers a tool that increases the understanding of the structure's behavior.
As the new shear design method has some challenges to be solved before it can be fully utilized for triaxial cases, the method has not yet been applied and demonstrated for real problems. However, the method has been verified by comparison with experimental results for biaxial problems where the results correspond very well with the experimental results.
