stress category and fatigue behavior of the proposed composite bridge deck.
In order to determine the influence of the concrete filling, the authors con-
ducted fatigue tests on partial steel specimens with plain corrugated steel
plates. The partial steel specimens and the steel-concrete composite deck
specimens showed that fatigue failure occurred in the tension part. The
research concluded that the fatigue behavior of the proposed steel-concrete
composite decks under sagging moment can be estimated based on the clas-
sical S-N approach, focusing on steel components. The structural behavior
and ultimate strength of steel-concrete composite bridge deck slab with pro-
filed sheeting were investigated by Kim and Jeong [ 1.60 , 1.61 ]. The study
[ 1.60 ] presented an experimental investigation on a steel-concrete compos-
ite bridge deck slab with profiled sheeting and perfobond shear connectors.
Two full-scale deck slab specimens cast onto three concrete blocks were fab-
ricated and tested under static loading to examine the ultimate load-carrying
capacity of the proposed deck slab system under sagging and hogging bend-
ing actions. The ultimate behavior of the full-scale deck slab specimens was
compared with that of simply supported deck specimens under hogging
bending only. In addition, the load-deflection behavior of the proposed
deck systemwas compared with that of a RC deck slab. The test results indi-
cated that the ultimate load-carrying capacity of the proposed deck system
was at least 220% greater than that of the RC deck system and that the deck
weighs about 23% less than the RC deck system. The study [ 1.61 ] investi-
gated experimentally the ultimate behavior of steel-concrete composite
deck slab system with profiled steel sheeting and perfobond rib shear con-
nectors. The experimental investigation aimed to develop a composite deck
slab for girder bridges that spans longer but weighs less than the conventional
RC deck slab. Eight deck specimens were tested with different shear span
lengths to evaluate the horizontal shear capacity of the proposed deck system
by using the empirical m-k method. The study also presented the results of
two full-scale deck slab specimens supported by a set of steel box blocks to
examine the ultimate load-carrying capacity of the proposed deck slab sys-
tem under sagging and hogging bending actions. It was found that the ulti-
mate strength and initial concrete cracking load of the proposed deck system
under hogging bending action were approximately 2.5 and 7.1 times greater
than those of an RC deck, respectively, while the deck weighed about 25%
less than RC deck systems.
Steel-concrete composite cable-stayed bridges were investigated numer-
ically by Pedro and Reis [ 1.62 ]. The composite deck and the concrete towers
were modeled by three node steel and concrete frame elements having seven
