Study on the Anti-seismic Performance of New Swing Structure System based on PUSHOVER

Swing structure is added to the current frame structure for forming the new swing structure system. In this paper, by taking the existing structure as an example, the anti-seismic performance of the new swing system is analyzed with pushover method and the current earthquake resistant design code, and influence of swing rigid frame with different stiffness ratios on the anti-seismic performance of the new structural system is discussed. According to the results, by setting swing rigid frame with different stiffness ratios, it can enhance the bearing capacity and ductility of the structural system remarkably, coordinate the deformation model of the structural system, give full play to the energy-dissipating capacity of the structure, and improve the anti-seismic performance of the structure.
