Structure's Analysis Of Large-Span Prestressed Concrete Bridge With Continuous Rigid Frame Stracture

This paper takes the JiuZhan Song HuaJiang Bridge in Ji Lin province as an object of study. The author designed,made,processed and tested to the plexiglass model and the bridge. Then author calculated and analyzed the results,as a result of the computer programs BSAS,SAP,QJX and NASTRAN. The author researched the force characteristics and structural behavior of large-span prestressed concrete bridges with continuous rigid frame structure,used the advanced theory and technology,materials,arts and crafts to resolve the practical matters in design and construction ,to optimize structure,and to provide credible technical data for the design and construction and maintenance of bridges.
