Abstract:
This paper provides a theoretical overview on the most influential theories for compression field models for shear and torsion. Special attention is given to the steel behavior because this is the point where the rotating-angle softened-truss model (RA-STM) and modified compression field theory (MCFT) depart. A new proposal for the steel model is presented. This proposal has the advantage of an embedded bar system, but it does not introduce additional complexity in the formulation. The steel model is based on tension stiffening behaviour. Several examples are presented, including a prestressed girder and a wall-type structure.
