As an external prestressed concrete box girder continuous rigid-frame bridge with the longest span in China, the Xiantan Bridge was reported in this paper for its special characteristics. The key points of the end cross beam for anchorage zone and deviation block for the de viator were introduced in detail for its design. The finite element models for them with 3D FEM were created to get the stress...
The Unity Bridge between Tanzania and Mozambique as the background project, the deviation block of external prestressing are analyzed with ANSYS software. When the deviators holes inner diameter are enlarged 1.5 times from 130 mm because the different deviators are applied, the concrete stresses and cracks state are introduced in detail, some suggestions for construction are presented. The results...
