| 摘 要： | 针对带肋筏板肋梁内力传统计算方法的局限性,采用无单元法建立筏板的刚度矩阵,同时采用有限元法计算肋梁的刚度矩阵,根据虚功原理,建立了双参数弹性地基上带肋筏板的无单元和有限元耦合计算方法,并通过实例计算验证了该法的可行性。

| Abstract: | Due to the limitation of the traditional calculating method of the internal power of the auxiliary beam of ribbed valve board,it takes element-free method to set up the stiffness matrix of valve board.Meanwhile it takes finite element method to calculate the stiffness matrix of ribbed beam.According to the virtual work principle,it sets up the biparametric element-free method and finite element coupling method of ribbed valve board on elastic foundation.Its feasibility is verified through examples. |
