Creep and Shrinkage Effects On Columns
| 项目名称： | Creep and Shrinkage Effects On Columns |
| 摘要： | Creep (CR) and Shrinkage (SH) forces due to long term prestress shortening produce imposed deformations on bridge columns at the bents. These deformations, in turn, produce column moments and shears which must be considered as part of the design process. The magnitude of the imposed deformations on the columns is in question and should be investigated by looking at various frame configurations and foundation types. Phenomena such as relaxation and foundation flexibility can reduce the effects of these forces and should be quantified. |
