Abstract.
Introduction Chloride-induced corrosion of steel bars has become one of the major causes of deterioration in many existing RC structures [1], structural engineers are faced with the challenge of assessing the vulnerability of such deteriorated structures and deciding on appropriate strengthening method to improve security guarantee and prolong service life of the structure.
FRP composites are becoming popular in the rehabilitation and strengthening for corroded RC structures in recent years [2-3], but single carbon FRP (CFRP) and glass FRP (GFRP) which have been adopted widely in present exist obvious disadvantage, for example, the deformation capacity of single CFRP is insufficient, and the strength of single GFRP isn’t high, which will restrict severely FRP composites to further using widely in civil engineering field.

By expanding the state function gp(X,t) to first-order approximation in a Taylor series of vector-valued functions and matrix-valued functions at a point E(X(t))=X(t)d, which is on the failure surface gp(X(t)d)=0, the expression of gp(X,t) is given
(19)
After knowing the first four order moments, that is to say mean value, variance, covariance, the third moment and the fourth moment of the basic random parameter X, the reliability index is defined as
(20)
The new reliability index with arbitrary distribution parameter can be given as
(21)
In engineering practice, the data available may only be sufficient to evaluate the first few moments such as mean, variance, the third moment, and the fourth moment of the random variables.
