Analysis of Vertical Isolation and Earthquake Prevention on Isolation Structure

Abstract:

Article Preview

According to Fast Fourier Transform we can work out main frequency of vertical vibration wave. Combining natural frequency of vibration of the structure we evaluate whether isolation layer have effect. Combine with a multi-tower with a large base structure located above subway, We use time history method and consider different vertical tensile-compressive stiffness of rubber bearing, Storey acceleration response of the structure under vertical earthquake and subway vibration was calculated. The result shows that it have no effect that isolation layer with regard to vertical earthquake, but have obvious effect to reduce subway vibration, At the same time, storey acceleration response is reduced markedly, comfort level can be increased greatly.
