Abstract:
The structural composite construction techniques find increasingly wide applications in bridges,
ramp, buildings and other different area throughout the world focusing on the composites systems.
Composite structures are created by combining two or more structural elements to act as a single
combined structural unit, where each element behaves in structurally efficient manner. Component
of composite structure in this study were composite slab, profile steel sheet, steel beam, shear
connector and reinforcement cages. From thus component the performance of connector was
studied in this works. The main purposes of this paper are to describe the structural performance
of demountable shear connectors in composite slab and steel beam with profile steel sheet analysis
through ABAQUS 6.14.
An accurate and efficient non-linear finite element model was developed to study the behavior of
demountable shear connectors prefabricated through deck. The material non-linearity of concrete,
connector, profiled steel sheet, reinforcement and steel beam were included in the finite element
model. A 24 specimen were carried out to investigate the load-slip behavior of the demountable
shear connectors in composite floor with profiled steel sheeting.
Result obtained from finite element analysis was carried out and verified with the experiment
results obtained from journal[1]. The capacity of shear connection result differences obtained
from journal to finite element analysis was 3.29% only, that means the parametric study used in
both investigations were nearest to each other in accuracy. The capacity of shear connection, load slip behavior of stud and failures modes were predicted.
In the result diameter of connector increase 19 to 22mm, then the capacity of shear connection
also increases by 26% and 17% in both open and re-entrant trough profile steel sheet respectively
and since height of sheet increase from 50 to 64mm the capacity of connector increases by10.6%
and 10.06% in open and re-entrant trough profile steel sheet respectively, similarly, since the
concrete grade increase C-40 to C-60 the capacity of shear connection again increases 26% and
20% with open and re-entrant profile steel sheet respectively and also the same effect with dilation
angle. The capacity of shear connection obtained from finite element analysis were compared with
the design strength calculated using European code for stud shear connector in composite slab
and steel beam with deck perpendicular to steel beam. It found that the design rules specified in
European code were generally conservative
