Research of the Influence of Dual Functional Hysteretic Dampers on Seismic Behavior of Structure with Big Openings

Abstract

The dissertation shows the formation and failure characteristic of the dual functional hysteretic dampers. SAP2000 was used to analyze the natural period of vibration and vibration mode of structures, the story drift under frequent earthquake and rare occurrence earthquake with different arrangements of dampers and the energy dissipation of dampers. The results show that dual functional hysteretic dampers keep elastic state under frequent earthquake while enter plastic state before the structure under rare occurrence earthquake.
