Health Assessment of Short and Medium Span Bridge Based on Risk Threshold

Health assessment of bridge is not only a hot point but also a difficult point in the modern bridge research. To health assessment of bridge, the current study mainly focus on the super large bridge and the large bridge, but researches on short and medium span bridge are less. According to the assessment data of carrying capacity in the completion of bridge, finite element model of main bridge of Dongfeng Street overpass based on completion status is established, and assessment methods and means applied to the health of short and medium span prestressed concrete bridges are proposed based on the concept of risk threshold.
