Seismic Simulation of Large Natural Draft Cooling Tower

Finite element analysis will be chosen to do the anti-seismic calculation of large natural draft cooling tower in most conditions.Due to the large size of cooling tower, however, it will take a long time to calculate with a fine meshed modal.At the same time, a thin meshed modal will not guarantee the accuracy of the results. In this paper, methods of finite element analysis with a fine meshed modal which focus on the week part of the structure is proposed. It is based on the holistic finite element analysis of a large natural draft cooling tower.This paper proves that deformation of the cooling tower appears mainly on the pillars.
