Frank J. Vecchio defined the original form of MCFT in 1982 from the testing of 30 reinforced concrete panels subjected to uniform strain states in a specially built tester. The theory of MCFT traces back through the compression field theory of 1978 to the Diagonal compression Field Theory of 1974. The definitive description of the MCFT is in the 1986 American Concrete Institute paper "The Modified Compression Field Theory for Reinforced Concrete Elements Subjected to Shear".
