| Abstract: | A new method called generalized displacement method, using new structural model taking into account the deformation of the nodal point and avoiding the disadvantage of stiffened nodal point model, is proposed here to calculate the displacement and the stress in adjecent point of thin-walled structure. The corres- ponding computer program is also developed and has been used to work out a series of problems with satisfactory results. The comparision of the results with anal- ytical solution or other results obtained from stiffened nodal point model shows that this method is very efficient to take into account warping effects of thin- walled structures. |
