| dc.description.abstract | The purpose of this study is to improve the curve damper. Due to its asymmetric shape, the strength of the tension side and the compression side is different. If the curve damper is buckled, the strength of the compression side will drop significantly. Therefore, an X-shaped curve damper is used, so that when one side of curve component is under compression, the other side of curve component is under tension. This configuration can prevent the damper from being subjected to a large external force. , the tension side still provides its strength. In addition, in order to improve the phenomenon that the stress of the curved damper is concentrated at the maximum bending moment, the design concept of fully stress is added in this study, so that each section can have a uniform stress distribution, and the material can be used more efficiently.
In order to verify the possibility of the above design, this study carried out a series of component tests for the X-shaped curve damper with different eccentricity, depth and thickness, and observed its mechanical behavior and hysteresis behavior. Load testing with repeated displacements in a moment frame. From the experimental results, it can be known that the phenomenon of obvious decrease of the strength of one side is effectively solved, and the stress is evenly distributed under the design concept of full stress reduction. And in the frame test, it can be seen that the installation of this energy dissipator can effectively increase the energy dissipation capacity of the flexural frame to more than 3 times. From the above results, this design can effectively increase the seismic performance of the flexural frame. | en_US |
