摘要
阐述三自由度平面杆系、六自由度空间杆系、七自由度空间梁单元、Hambly平面梁格、实体有限元及空间网格分析方法的特点,分析了桥梁设计验算中存在的问题。通过比较各分析方法,得出精细化分析方法可使箱形结构桥梁设计得更经济的结论。
The article sets forth the characteristic of 3-degree freedom planar linkage, 6-degree freedom spatial linkage, 7-degree freedom girder element, Hambly plane grillage, solid finite element and spatial grid analysis method, and analyzes the existing problems in bridge design calculation. According to the comparison of various analysis methods, the result shows that the refining analysis method can make the design of structural bridge more economic.
