| 中文摘要: |
| 收缩徐变作为混凝土结构固有特性,随着时间地延伸，它会不断地变化。尤其针对一些比较敏感的混凝土结构，如悬臂端、预应力混凝土连续梁等,其收缩徐变影响更为明显。本文以一工程实例为背景，利用有限元软件Midas进行桥梁模拟，通过对不同收缩徐变情况的探讨，得出混凝土收缩徐变对系杆拱桥的影响。 |
| 英文摘要: |
| Shrinkage and creep are the inherent properties of concrete, and it will change continuously especially for some of the more sensitive concrete structure, such as cantilever end, prestressed concrete continuous beam and so on , its effect is more obvious. This thesis takesan engineering example as the background, building bridge model with the finite element software Midas, and exploring different conditions of shrinkage and creep , getting the influenceof concrete shrinkage and creep on the tied arch bridge. |
