| 摘 要： | 梁格法是借用计算机来分析桥梁上部结构的一种比较实用有效的空间分析方法,但传统梁格法受模型及网格划分和单元刚度计算复杂性的限制,特别是在多格式箱梁中截面特性计算难度大,在桥梁电算方面未能得到广泛运用.本文基于梁格法的基本原理,建立空间梁格模型,文章最后通过算例验证了该模型的有效性和实用性.

| Abstract: | Although grillage method is an effective method for analyzing bridge deck by computer,it has not been widely used on computer calculation of bridges beacause of the restriction of traditional grillage model and the complexity of meshing and the element stiffness compution,especially on the complexity of element stiffness of multi-cell box-girder.Based on basic principles of grillage method,space grillage model is builded,and its effectiveness is verified. |
