Grey system method for predictingremaining service life of existingR.C. structures
Performance experiments of R.C.columns with corroded rebar
Further Research Aspects
Zhao Lab. of Structural Safety , Nagoya Institute of Technology
Accelerated electrochemicalcorrosion of rebar
A practical and efficient algorithm tocalculate skeleton curves of reinforcedconcrete members with corroded rebar ispresented.
Models and expressions of the influence of corrosion extent onanti-seismic performance and reliability of R.C. structures
Models and expressions of the influence of corrosion extent onanti-fatigue performance and reliability of R.C. structures
Bearing capacity, rigidity,ductility and energydissipation characteristicsof members are analyzed.
The goal of structural design is to ensure appropriatesafety, serviceability, durability and economy ofstructures. Durability evaluation of existing R.C.structures is an important part of research ondurability of R.C. structures.
