Computer-aided approaches for the efficient development of suitable stress fields are useful tools for the structural design of concrete structures. The paper describes a new procedure that is used within a previously proposed approach for the automatic generation of strut-and-tie models. Once the geometry of the strut-and-tie model is known, the stress fields can be created. A new method is also proposed to generate stress fields characterized by rectangular compression fields and nodes in a pseudo-hydrostatic stress state.
