dc.description.abstractA significant amount of seismic energy is imparted to the structures during earthquakes. Theenergy spreads within the structure and transforms in various energy forms as dissipatedthrough the structure. The conventional seismic design provides specific ductile regions,namely plastic hinges, on structural elements. Therefore, the energy dissipation capacities ofthe structural elements and the structure enhance. However, this approach accepts that thedeformations will concentrate on the plastic hinge zones and severe damage may occur onstructural elements within deformation limits that are defined by the seismic codes. The modernseismic design aims to dissipate a large portion of the seismic input energy by installing energydissipating devices (EDDs) to the structure. Thus, deformation concentrates on EDDs whichcan be replaced after an earthquake, and energy demand for structural elements is decreased.Lead extrusion damper (LED) is a passive EDD that utilizes the hysteretic behavior of lead. Inthis paper, the preliminary results of the developed three-dimensional finite element model(FEM) for a LED is presented. The results obtained from the finite element analysis (FEA) werecompared with the experimental ones in which LEDs were exposed to sinusoidal displacements.Also, the applicability of the developed FEM was checked for different component dimensionsgiven in the literature. The comparison study yielded a satisfactory consistency. Additionally,the maximum relative difference obtained for the literature devices was reduced to 12% from39% by the developed FEM.
