This calibration method adapts the K&C model for Ultra-High Performance Concrete (UHPC) with compressive strengths of 150-250 MPa, using empirical models from Attard & Setunge (1996) and Samani & Attard (2012) to predict triaxial behavior without requiring laboratory triaxial test data. Results should be validated against experimental data for critical applications.
