Feasibility assessment of prestressed reactive powder concrete box-girder bridge with corrugated steel webs

The prestressed concrete box-girder bridge with corrugated steel webs(CBCW) is taken as a research prototype in this paper. The authors present the new type model of prestressed reactive powder concrete box-girder bridge with corrugated steel webs (RPCBCW)based on the prototype design and reactive powder concrete theory. Comparative analysis of this two structures are carried out at all aspects of the properties of materials, the deflection and mechanical property of structure within the regular service conditions, economic, efficiency and design-construct so on for the evaluation of practicability to RPCBCW. The analysis presents: when the CBCW and RPCBCW bear equivalent applied load, the RPCBCW shows superior mechanical property, visible economic efficiency. Furthermore, the appealing design becomes more light and the construction more standardized and fast.
