| 摘 要： | 根据Novozhilor截锥壳几何方程及薄壁弯梁桥的特点 ,构造了一种线位移和转角各自独立插值的四边形截锥壳单元 ,并编制了用于计算薄壁弯梁桥的有限元程序。用该程序对一简支弯箱梁进行验算 ,理论值与试验值符合良好 ,从而验证了该模型是可靠的

| Abstract: | The thin?walled curved?box beam bridge using 3D FEM is analyzed in the paper.A quadrangular frustum of conical shell element is proposed.It is based on the Reissner?Mindlin thick plate theory.The displacements and rotations of the element are varied independently.At same time,a computer program is developed for the curved beam bridges.A model of simply supported curved?box beam bridge is made for test.The computing results are compared with the test one and other data.It is found that the theoretical results are well agreed with that of the test one. |
