| Abstract: | By finite element analysis software ANSYS , the influences made by interaction between foundation and cooling tower to the hyperbolic cooling tower＇s dynamic characteristic have been analyzed in this paper. Based on the results of the above research, the influence of the damping ratio to the structural seismic effect has been analyzed. Then, some concerns of the design of the large scale cooling tower have been put forward. The conclusions could be the used to the similar project. |
