Adaptive Stress Field Models: Formulation and Validation
Stress field models or strut-and-tie models are commonly recognized as powerful tools for the development of consistent design methods for structural concrete discontinuity regions. Serviceability and ductility topics are usually indirectly checked through an adequate model selection, together with appropriate reinforcement details. Stress field models are an alternative to finite element analyses, which are frequently referred to as the main tool for the assessment of the aforementioned topics. The proposed approach, called Adaptive Stress Field Models, extends the application of stress-field-based models for the nonlinear analysis of structural concrete discontinuity regions, allowing a consistent study of service behavior, ductility and, more generally, model assessment topics. The numerical results are compared with the test and nonlinear finite element analysis results.
