Abstract

Friction plays an important role in creating damping mechanism in structures. In this paper a study was conducted to analyze coulomb friction damping and frictional energy dissipation mechanism with stone blocks in a single degree of freedom system by discrete and continuum modeling in finite element-based software ABAQUS. Discrete and continuum modeling approach was used in this study. It was found that both approaches gave similar results.
