In our country, buildings are facing the severe threat of earthquake disaster, almost all buildings have to carry out structural seismic design. Shear wall structure is one of the common structural systems of high-rise building, in order to study the isolation effect of high aspect ratio structure and understand the reason of isolation effect, under the action of horizontal force, Timushenko beam can assume the deformation mode of bending-shear type, which is close to the deformation characteristics of shear wall structure. The bottom isolation shear wall structure has the characteristics of bending-shear lateral displacement curve under the action of strong earthquake, and its mechanical characteristics are similar to Timoshenko beams. How to accurately evaluate the importance and reliability of many influencing factors, this paper adopts the fuzzy analytic hierarchy process to analyze the dynamic characteristics before and after the seismic isolation of the cantilever Timoshenko beam of the bending-shear structure, determine the weight of each evaluation item for the analysis of the damping effect of the whole structure. It is concluded that prolonging the period, reducing the participation mass coefficient of high-order mode shapes and increasing the damping ratio of the system are the three major factors for vibration isolation technology.
