A calculation procedure is developed for estimating crack shear stresses and crack slip displacements from average strain measurements made on reinforced concrete panels. Several series of previously tested panels are examined and crack shear-slip data are extracted. These data are compared against the predictions of previously developed crack slip models.; VecTor2 was used to analyse a series of panels, beams and shear walls subjected to shear and cyclic loads. Comparison with experimental results is made in terms of load-deformation response and ultimate strength. Good agreement with the experimental results is achieved.; Deficiencies in the analytical models are determined. Examples illustrating the similarity between the experimental and analytical results are also presented.; It is shown that rigorously accounting for crack slip displacements results in a better representation of various subtle aspects of behaviour, such as the failure mode and the capacity of elements to deform and redistribute load.
