Abstract
In order to research the high-rise building isolation structure of a high-rise building aseismic capacity role ansys finite element software, to fixed high-rise buildings and isolated high-rise building the modal analysis. The results showed that the natural frequency of the structure with the increase of the order number increases; Isolation structure of isolation layer uses of a lot of vibration isolation energy; Through the upper structure and foundation in building between has enough safe and reliable set of isolation system, form, make the building and the flexible bottom separated, in order to prolong the foundation of structural system of the natural vibration peri- od. Reduce the upper structure of the earthquake energy output, so as to reduce the ring buildings; Vibration isolation node acceleration obviously decrease; After an earthquake happened between the displacement of the tiny reduction. The simulation results indicate that the seismic damage to the horizontal seismic damage is given priority to, the building must decide intensity damage; Isolation layer absorption in the large amounts of energy, isolation upper structure absolute acceleration is reduced and base isolation system can reduce the level of structure the earthquake action.关键词
