| Abstract |
This study proposes a three-dimensional yield honeycomb damper capable of stably dissipating energy during earthquake disasters. The honeycomb structure is the most stable structural geometry derived from nature and has attracted interest from many research fields, including structural engineering. Such honeycomb structures have frequently been applied in the form of dampers to resist earthquakes. However, it was recognized that these structures, being composed of planar elements, have the disadvantage of only being able to dissipate loads in the shear direction. Unlike previously proposed planar dampers, the three-dimensional yield honeycomb damper utilizes a three-dimensional honeycomb structure, designed to maintain energy dissipation capabilities even under various deformation conditions. The variables selected were the number of base polygonal faces, the damper length, and the base diameter, and 30 dampers were designed. To verify performance, cyclic loading was applied, and a three-dimensional nonlinear analysis was performed using the ABAQUS program to derive force-displacement hysteresis curves. Using these curves, responses such as maximum load and energy dissipation were derived, and ratio graphs were created to verify the variation in response for each variable, thereby analyzing the performance. Through this, it was confirmed that the most important factor is the slenderness ratio of the columns constituting the honeycomb damper. In addition, the excellent honeycomb structure exhibited behavior in which the load was distributed throughout the structure, and the results of this study are expected to serve as basic data for the design and performance evaluation of yield dampers with honeycomb structures. |
