Prestressed normal concrete (PC) box-girder with corrugated steel webs has been widely used in bridge engineering because of its favourable properties and wins general recognition of bridge practitioners, but researches on externally prestressed reactive powder concrete (RPC) box-girder with corrugated steel webs are still rare. In this paper, the experiment and ABAQUS finite element analysis considering materials nonlinearity are performed to study the mechanical properties of externally prestressed RPC box-girder with corrugated steel webs during its whole bending process. The experimental results show that compared with externally prestressed normal concrete (PC) box-girder with corrugated steel webs, the externally prestressed RPC box-girder with corrugated steel webs has higher ultimate bearing capacity, higher cracking strength, better anti-cracking performance and durability. The ABQUS finite element analysis results have good agreement with the test results and the model of this article for the analysis of the whole bending process of externally prestressed RPC box-girder with corrugated steel webs is feasible.
