| 摘 要： | 在预应力深梁拉压杆模型的基础上,根据结构局部分析原理,研究提出了预应力连续梁局部等效转化成预应力深梁的局部拉压杆模型分析方法。利用此方法对某预应力连续梁桥局部梁段建立拉压杆模型,验算配筋和强度。结果表明:利用文中提出的方法建立拉压杆模型用于预应力连续梁桥局部分析是合理有效的。 |

| Abstract: | On the basis of the strut-and-tie model for prestressed deep girder and on the principal of local analysis of structure,this paper makes a study of and proposes a local analysis method of the strut-and-tie model for prestressed continuous girder with its local part equivalently transferred into the prestressed deep girder.By the method herewith,the paper establishes a strut-and-tie model for segment of the local part of a prestressed continuous girder bridge to review the reinforcement layout and strength of the bridge.The results show that the establishment and application of the model according to the method in the paper to the local analysis of the prestressed continuous girder bridge are reasonable and effective. |
| Keywords: | prestressed continuous girder bridge box girder strut-and-tie model deep girder local analysis |
