Abstract:
The introduction of energy dissipating devices as passive dampers in structural systems under earthquake excitation is intended to reduce structural deformation and in certain cases to reduce the risk of damage to equipment attached to the structural system. In seismic design, the input energy of an earthquake is typically dissipated through hysteretic behaviour of structural members, which allows the structure to undergo inelastic deformations without compromising the stability of the structure. The energy dissipation demand on principal members of the structure can be reduced by transferring this energy dissipation demand to the passive dampers. Viscoelastic, frictional and elasto-plastic elements are among the most commonly employed components of energy dissipating devices. All these devices provide the desired damping capability to the structural system and, eventually, increase the stiffness of the structural system. In this paper the generic criteria and numerical simulation for designing yielding devices, including a description of the engineering characteristics of the devices together with a description of important device-to-structure connectivities and flexibilities are presented.
