This publication presents the principles and validation of the Compatible Stress Field Method (CSFM). This new method can be used for the design and assessment of any concrete structure subjected to in-plane loading, being particularly suited for the dimensioning of so-called discontinuity regions, such as corbels, deep beams, walls with openings, dapped beam-ends and frame corners. The CSFM represents
a significant progress for structural engineering practice, as it allows efficiently checking all design code provisions, including serviceability, load-deformation and deformation capacity aspects even for concrete members with complex geometry. The method is based on Finite Element Analysis and uses only basic material parameters used in standard structural concrete design.
The results of the CSFM for a set of verification examples are presented and discussed, including the influence of the main parameters of the method and its underlying models. The results are compared to a wide range of analytical solutions, design code provisions as well as experimental results, showing a good agreement.
