Input Value Correlation in Chloride Ion Ingress Modelling and Concrete Structures Reliability

摘要

The assessment of service life of a structure can be performed via mathematical modelling -either analytical or numerical and it can be viewed as a necessary pre-requisite for life-cycle engineering decisions. Many works concerning the modelling and testing of degradation effects for engineering systems are reported in the literature. The present paper discusses the degradation modelling of reinforced concrete structures and concentrates on the damage they sustain due to chloride ingress, namely a special aspect: the influence of statistical correlation among input variables on the reliability.
