Dynamic response of low profile container crane under wind excitation
In general, several external actions must be considered for design the lifting equipment; some of these are: the weight of the component, the pay load and its dynamic actions, the actions induced by the earthquake, the load produced by the snow and wind. In particular, concerning the action induced by the wind, the problem is studied and dealt by standards considering an equivalent static load applied to the structure. This action, essentially a force, depends on the wind speed, so on the specific pressure, the frontal area on which it acts and a aerodynamic coefficient which depends on the shape of the component. The structures that constitute the lifting equipment also for economic considerations, are increasingly slender and tall and thus their first natural frequencies values are very low. For example, in the container crane these values below to 5 Hz.
