Reliability Analysis of Fatigue Crack Growth in Plain Concrete

Abstract

Civil engineers know that fatigue indicates the
majority of structural failures. In plain and reinforced
concrete structures, fatigue might account for excessive
deformation, excessive of crack widths, de-bonding of
reinforcement and rupture of the reinforcement, all of these
can lead to structural collapse. Fatigue crack propagation
can be a method to predict a remaining life of structures.
Herein some works that have been done will be shown in
order to analyse the fatigue crack growth for plain concrete
specimens. The goals of this study are to estimate the critical
crack length and remaining life of a plain concrete
specimen, determine the state of the specimen either having
failed or being safe using first order reliability method
(FORM) and assess which parameter has most influence on
the reliability index
