Numerical investigation on scaling a pure friction

Coulomb friction systems can be correctly scaled in shaking table model tests. • The un-scaled gravity causes an incorrect friction force and response errors. • The friction coefficient is adjusted to offset the misestimated gravity. • The uneven friction distribution causes response errors of scaled models. •

Numerical investigation on scaling a pure friction

Many Coulomb friction-based devices have been used for seismic isolation of modern civil structures. Aiming at a practical problem that if the friction action could be scaled in a shaking table model test, a base isolation system using Coulomb friction was numerically scaled in different ways by considering the gravity distortion, friction distribution and other influence factors.
