Because shock absorbers are an important component of high-rise buildings, it is essential to be able to detect damage to them. Viscoelastic (VE) dampers, as a common shock absorber, directly affect the safety and reliability of VE materials over the entire life of structures. This study is aimed at optimizing a high-dissipation VE material with excellent aging resistance. The VE damper was developed after aging of anti-aging and high-dissipation VE materials. To analyze the damping and mechanical properties of the VE dampers in detail, mechanical performance testing was conducted on VE dampers under various loading conditions, demonstrating that dampers had excellent mechanical properties and confirming the anti-aging properties of the VE materials. In addition, a fractional standard linear solid model based on damage modification is proposed, and aging is considered in the mathematical model of VE dampers as an indispensable factor. After the simulated value is compared to the experimental results, it is found that the fractional mathematical model that involves the aging factor precisely describes the real-time mechanical properties of the VE damper.
