Assessment of an Existing Prestressed R.C. Bridge According to fib Bulletin 80
摘要
Fib Bulletin 80 proposes two methods for the recalibration of the partial safety factors specific for existing reinforced concrete structures and infrastructures taking into account different issues: the residual service life, information deriving from tests, measurements of variable actions and lower target reliability according to economical and human safety criteria. The methods presented in fib Bulletin 80 have been used to assess an existing prestressed concrete bridge built in the 90s. Successively, the results are compared to the outcomes achieved using the approach of EN1990.
