ASYMPTOTIC ANALYSES OF DYNAMIC RESPONSE OF HYPERBOLIC COOLING TOWER SHELLS WITH RING-STIFFENERS—PERTURBATION FINITE ELEMENT SOLUTION

Asymptotic analyses of dynamic response of hyperbolic cooling tower shells with ring-stiffeners perturbation finite element solution

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 of hyperbolic cooling tower shell with ring-stiffeners. The results are compared with those of finite element numerical method and show that the method has the advantages of clear physical idea and convenience of calculation and the accuracy of results is assured. This paper was published in the second computational mechanics conference in Shanghai, China, Aug., 1986.
