Nonlinear Bond Model for the Dowel Action considering the Fatigue Damage Effect

Nonlinear Bond Model for the Dowel Action considering the Fatigue Damage Effect

To investigate the mechanical properties of dowel action under fatigue loads, 3 reinforced concrete specimens with different bar diameters (12 mm, 20 mm, and 25 mm) were subjected to the fatigue loading and were designed to investigate the attenuation character of dowel action and the fatigue failur...
