【 摘 要 】

In order to avoid the disaster caused by earthquake and wind-induced vibration to the building structure or bridge structure, this essay puts forward a new type of external viscous shear dampers. The authors did correlation tests of frequency and fatigue tests, getting the mechanical properties of the damper. And by comparison with numericals simulation and engineering verifications, this paper draws these conclusions: firstly, the numerical simulation results are consistent well with the experimental results, which verifies the validity of the theoretical model; secondly, this external viscous shear type damper can absorb large energy, and the shape of its hysteresis curve is full. It shows that this kind of damper can make the structure have good seismic performance, which is of benefit to the building to achieve the purpose of not collapsing in a large earthquake. What's more, it also shows that this damper can enhance the seismic performance of the building structure or bridge engineering.
