RESEARCH ON THE DESIGN AND CALCULATION METHOD OF PREFABRICATED AND POST-TENSIONED PRESTRESSED SIMPLY SUPPORTED GIRDER BRIDGES
The design of small span bridges is commonly found in municipal engineering projects.Taking a typical cross river section project of a municipal project as the research object,a 16 meter prefabricated post ten-sioned prestressed concrete simply supported slab beam bridge was selected for cross river bridge design,analysis,and verification.The following conclusions were obtained:Firstly,a two-dimensional beam element design verifica-tion method was provided for the design verification of the prefabricated post tensioned prestressed concrete simply supported slab beam bridge;Secondly,the rationality of the bridge design in this project was verified by comparing it with the regulatory requirements;Finally,the research findings can provide relevant basis for selecting the form of"prefabricated prestressed concrete simply supported slab"for bridges with a span of no more than 16 meter.
