Abstract
This study deals with the enhancement of the longitudinal shear interaction at the
concrete-profiled steel sheeting interface of composite slabs by using shear
connectors.
The push out and flexural tests are carried out with the same shear connection
details. Fourteen push out specimens with different configurations were
prepared, of which five specimens with steel deck thickness of 0.7 mm and nine
specimens with steel deck thickness of 1.2 mm. For each profiled steel sheeting
thickness one specimen is assigned as a control specimen and the other
specimens were prepared by using different types of shear connectors such as
self-drilling screws with different lengths and different spacings, also cold
formed members were used with different shapes (U & C) and different
spacings. Eleven large scale specimens with different configurations were
prepared. Four specimens were prepared with profiled steel sheeting of 0.7 mm
thickness and seven specimens with profiled steel sheeting thickness of 1.2 mm.
One control specimen for each profiled steel sheeting thickness was also
prepared. The other specimens were prepared by using different types of shear
connectors such as self-drilling screws with different lengths and different
spacings, also cold formed members were used with different shapes (U & C)
and different spacings.
The test results show that the failure mode of composite slabs was improved
where ductile behavior was observed. Also the load carrying capacity can be
increased by the presence of the shear connectors. The load performance of the
slabs is also affected by changing the profiled steel sheeting thickness.
