连续梁施工分析例题（征集daan-限ansys），奖励积分5分

上传一个连续梁施工方面的题目（具体见附件，未附答案），徐变系数大家可以自己指定，有兴趣的可以探讨下

三跨梁在支架上分三次现浇，杆件在重q=10T/M，跨径、分段见图。第Ⅰ阶段（假定6月1日）先浇注第一梁段a，经7天后（6月8日）梁段a落架，引起内力如图。过7天后（6月15日）第Ⅱ阶段开始，浇注第二梁段b与第一梁段a相联，在建筑7天后（6月22日）梁段b落架（假定这时第二梁段与第一梁段相联起作用），由此引起内力见图。再过7天后（6月29日）第Ⅲ阶段开始，浇注第三梁段c与第二梁段b相联，在浇注7天后（7月6日）梁段c落架（假定这时第三梁段c与第二梁段b相联起作用），有关徐变系数从表中查得。求2、4点的成桥后14天的弯矩。

当然，ansys没有直接计算混凝土徐变的功能，所以首先要建立自己的徐变模型，然后再建立梁单元或实体单元加入前面的徐变模型
下面是针对本题ansys建立的梁单元模型，仅供参考

问题基本解决——这是本人毕业论文的部分
三跨梁在支架上分三次现浇，杆件在重q=10T/M，跨径、分段见图。第Ⅰ阶段（假定6月1日）先浇注第一梁段a，经7天后（6月8日）梁段a落架，引起内力如图。过7天后（6月15日）第Ⅱ阶段开始，浇注第二梁段b与第一梁段a相联，在建筑7天后（6月22日）梁段b落架（假定这时第二梁段与第一梁段相联起作用），由此引起内力见图。再过7天后（6月29日）第Ⅲ阶段开始，浇注第三梁段c与第二梁段b相联，在浇注7天后（7月6日）梁段c落架（假定这时第三梁段c与第二梁段b相联起作用），有关徐变系数从表中查得。求2、4点的终极弯矩。(见《预应力T型刚构式桥》P176)

计算点      理论值        Beam23结果        相对误差%                      Solid45结果                       相对误差%
2点弯矩        -832.81        -858.844                           3.1                         838.629                           0.7
4点弯矩        -898.6        -908.143                            1.1                          885.445                               1.5
第一阶段（7天~21天）为静定结构体系，单悬臂状态，徐变不引起内力重分布。第二阶段（21天~35天），在第二梁段与第一梁段合龙后，由于两个梁段的徐变发展不同，引起内力重分布。第三阶段（35天~ ），三短梁由于徐变发展的不同，仍会有内力重分布的发生。同样的徐变系数较大的梁段发生的徐变也较大 ，内力变化较大。
通过比较弹性变形和徐变弯矩，可以看出：在徐变次内力的影响下，两个支座的弯矩显著的增长。实体单元应力与理论值相对误差在6%左右，由图可以看出在弹变中有局部应力偏差较大，尤其在支座与梁体接触处，但到了徐变变形里就有所缓和，可见徐变能够削减局部应力的峰值。

分别采用梁单元和实体单元建立模型。对比结果见上

高手啊,在别的论坛上也看到很多你的帖子,请水幽寒兄多多指点!!!

共享一下徐变部分命令流吧

斑竹，能否把整个命令流贴上来，以便大家参考学习。:victory:

要用到二次开发吧，你以上的图形是土木模块的吧。

我怎么不能下附件啊

有限制没有粘完
