Review of predictive capabilities of JRC-JCS model in engineering practice

The database used in developing the Barton-Bandis joint model is reviewed. It is shown how tilt testing to obtain JRC is extrapolated both in terms of stress and sample size. Field measurement of JRC is demonstrated, and relationships with J r in the Q-system are developed. Constitutive modelling of shear stress-displacement, dilation and shear reversal are also described
