Abstract

Recent application researches on external pre-stressing method of composite structures have been conducted to explore its advantages. An external pre-stress could improve mechanical behavior and maintenance, and is economically efficient. In this paper, the Incremental Deformation Method (IDM) was proposed to analyze the elasto-plastic flexural behavior of externally pre-stressed composite bridge with consideration for the material's nonlinearity. This method was verified with experimental results.
