| Abstract: | Tbe random response of drilling derricks under the action ofwind load was studied by using the probabilistic method and the theory of structure dynamics. Based on the first excursion probability, the dynamic reliability of a drilling derrick for a 3200 meter well was obtained by using the Poisson method and modified Vanmarcke equation. A computer program based on this method was used in a real derrick calculation. |
