摘要: In this paper, a new analysing method called perturbationalfinite 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.

关键词: nonlocal Timoshenko beam theory, precise integrator method, embedded curved carbon nanotube, nonlinear vibration, harmonic load
