Unified Theory of Concrete Structures develops an integratedtheory that encompasses the various stress states experienced byboth RC & PC structures under the various loading conditions ofbending, axial load, shear and torsion. Upon synthesis, the newrational theories replace the many empirical formulas currently inuse for shear, torsion and membrane stress.
The unified theory is divided into six model components: a) thestruts-and-ties model, b) the equilibrium (plasticity) truss model,c) the Bernoulli compatibility truss model, d) the Mohrcompatibility truss model, e) the softened truss model, and f) thesoftened membrane model. Hsu presents the six models as rationaltools for the solution of the four basic types of stress, focusingon the significance of their intrinsic consistencies and theirinter-relationships. Because of its inherent rationality, thisunified theory of reinforced concrete can serve as the basis forthe formulation of a universal and international design code.
* Includes an appendix and accompanying website hosting theauthors' finite element program SCS along with instructionsand examples
