| 摘 要： | In this paper,a new analysing method called perturbational finite element is suggested,by means of which we calculate the dynamic behaviour and response to turbulent wind ofhyperbolic cooling tower shell with ring-stiffeners.The results are compared with those offinite element numerical method and show that the method has the advantages of clearphysical idea and convenience of calculation and the accuracy of results is assured. |
