3-Dimensional Finite Element Analysisof Curved Thin-walled Box Girders
摘要
Abstract
The strain-displacement relationship of curved box girder,which is based upon thedifferential geometry and the theory of warping and torsion of thin-walled curved box gird ers,is derived in this paper. By means of the energy principal,and the element sfiffness ma trix of curved box girder and the equivalent nodal load column matrix are established of thispaper element deformation model. The numerical results show that the theory presented inthis paper is correct,easy and practical.关键词
