| 摘 要： | 采用有限元法对温度作用等截面箱梁竖向温度应力进行了详细的分析,推导了一般公式,温度变化规律较为吻合,通过综合性桥梁结构设计与施工软件桥梁博士对是否考虑温度应力作用情况进行对比分析,以此为依据,说明温度应力在箱梁结构设计中的不可忽视性。

| Abstract: | The paper has the detailed analysis of the vertical temperature stress of the equal section box girder of the temperature effect by adopting the finite element method,induces the general formula and it is consistent with the temperature change law,and compares and analyzes whether the temperature stress should be considered by the design for the comprehensive bridge structure and the construction software Dr.Bridge,and indicates the temperature stress should not be neglected in the design for the box girder structure based on the above-mentioned part. |
