Abstract
This paper takes the wooden structure of Guangyue Tower as an example, selects ANSYS finite element software, establishes the upper wooden structure and the finite element model considering the whole structure of the high platform respectively, uses the incremental dynamic analysis method, and uses different ground motion intensity parameters to carry on the dynamic time history analysis to it. The results show that the existence of the high platform magnifies the displacement response of the wooden structure, which is not conducive to the seismic resistance of the wooden structure; IDA curve expressed by ground motion intensity parameter PGA can better reflect the overall change of the structure, which is helpful to improve the effectiveness of seismic performance evaluation of Guangyue Tower.
