| Abstract: | Considering engineering practice,the partial pressure problem of fiat anchors has its own speciality in the simple sup- ported-continuous girder bridge.The finite element program was used to analyse the problem in terms of four different con- ditions from the aspects of lay-out depth of the toothed bar and the reinforcing fabric under the flat anchor.The stress dis- tribution under the flat anchors for different conditions was studied,and the cracking behavior,cracking mechanism and cracking process were all found out. |
