%X The hybrid viscoelastic damper (HVD) described in this paper is primarily composed of rubber, steel bars, and steel plates. Due to the hyperelasticity of rubber, the HVD can be utilized after an earthquake, and it is simple to replace steel bar components that have yielded as a result of exposure to earthquake loads. Prototypes of the HVD were put through a number of laboratory tests applying dynamic loading in order to validate and analyze its mechanical behaviors, particularly the impact of displacement amplitude and loading frequency. The experiments showed that the functioning mechanism and configuration of the components were feasible and reasonable. At a frequency of 0.89 Hz (or, 1/(1.5(T1))) with a loading displacement of 16.6mm (or, 0.33 MCER), the force can reach 79.37kN with a damping ratio of 26.19, and at a loading displacement of 33.5mm (or, 0.67 MCER), the force can reach 143.9kN with a damping ratio of 21.57. At a natural frequency of 1.335 Hz (or, 1/T1), the force and damping ratio can reach 81.42 kN and 25.23, respectively. The deformation capacity and force capacity of the HVD prototype can be predicted accurately using the ABAQUS software and reached regulations for producing damper devices. © 2024 by authors, all rights reserved.
