Aims: This study deals with the enhancement of the longitudinal shear interaction at the concreteprofiled
steel sheeting interface of composite slab by using shear connectors. The push out and
flexural tests are carried out with the same shear connection details.
Place and Duration of Study: The test is carried out in RC laboratory at Faculty of Engineering in
Benha, Benha University, Egypt, between May 2014 and March 2015.
Methodology: Fourteen push out specimens with different configurations were built in, 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 enhanced with different types of shear connectors such as selfdrilling
screws with different length and spacing, cold formed members with different shapes (U&C)
and different spacing. 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 enhanced with different
types of shear connectors: self-drilling screws with different length and spacing and cold formed
members with different shapes (U&C) with different spacing. |
