文摘
- •
Different models for friction pendulum isolators are compared.
- •
The friction coefficient is considered varying with velocity and axial force.
- •
2-DOF systems subjected to horizontal and vertical ground motions are studied.
- •
Nonlinear dynamic analyses are performed considering near field records.
- •
The influence of vertical component on the collapse acceleration is examined.
