Abstract
En 中文
Lateral-torsional coupling effect leads to poor seismic performance in eccentric structures, while traditional methods have their own limitations. This paper proposes an inerter-based solution to improve the seismic performance and develops the corresponding optimal design method. Comparative analysis under different control strategies is conducted to evaluate the vibration-suppressing effect of the inerter system by finite element simulation. The results show that inerter system can significantly reduce the seismic response, especially the torsional response, and exhibits greater efficiency than viscous damper with the same damping coefficient. Thus, the proposed inerter-based solution can effectively control the vibration of eccentric structures.
