Abstract
This design is according to the requirements of the design and design
specification, according to the teacher and his design, for the precast concrete
T beam, for the first simply after continuous structure. The prestressed concrete
T shaped beam bridge has the advantages of simple structure, clear loading, saving
material, installing and installing, and crossing over ability.. The bridge is
pided into 5 pieces, 4 span, each span 40m, and the upper structure is continuous
beam. The bridge uses the separation type roadbed, the design only considers the
design of the half roadbed. The construction method is precast T beam
Method.
Calculation of the upper structure of the proposed T beam section, very
detailed unit pision of 4 x 40m span, the calculation of the internal force
of dead load and live load force, full bridge by Midas are calculated, all designed
to drawings by AutoCAD drawing and computer filing, typesetting, print out the
diagram and thesis.In addition, an English document is also translated
“ Full-Range Analysis of Multi-Span Prestressed Concrete Segmental Bridges”
Keywords: grade separated pre-stressed concrete continuous girder bridge
