Abstract:
In the study of ultimate moment modification of PPC hyperstatic structures, the ultimate moment modification can be calculated theoretically according to curvature ductility. At the same time, the moment modification is influenced by two factors, one is maximum crack width in service loading, the other is the time at which the first hinge takes place. At last, the formulae for calculating moment modification of PPC hyperstatic structures are offered.
