| Abstract: | in this paper,the stability analysis of oilfield 'A' form derrick are analysed using the stochastic finite element method. The one -order and two-order sensitivities are calculated when the serevel structural parameters of elements are changed randomly.The random structural ultimate load formula of the derrick are given out.All results and conclusions in the paper are quite valuable for designing 4 new type oilfield derrick in future. |
