ANALYSIS ON THE STABILITY OF OILFIELD ‘A’ FORM DERRICK |
| |
| Abstract: | , In order to calculate the buckling load of ‘A’ form derrick and the sensitivities of its elements' many structural parameters, in this paper, the one order and two order sensitivities of many parameters against buckling load are calculated when the several structural parameters of the elements are changed randomly using the random perturbation finite element method of buckling analysis. Finally, the random structural buckling load's concrete expressive formula of the derrick are given out. |
