Design of 30m T-beam bridge
ABSTRACT
The prestressed concrete T-beam bridge has the advantages of simple structure, prefabrication of standard component installation, shortened construction period, less equipment required, strong resistance to cracking and fatigue, and is widely used in the construction of small and medium span bridges. This graduation design adopts the form of prestressed concrete T beam. Through reviewing the design and construction literature of many prestressed concrete T beams, this paper briefly introduces the development of prestressed concrete bridge, the design flow and content of prestressed concrete T beam, and post-tensioning method. Construction process and related content of prefabrication installation.
Key words：Prestressed concrete T-beam bridge; Post-tensioning; The design process
