Experimental Investigation and Comparison of Composite Slab with Perpendicular and Skew Type Steel Decking

Author(s): S. Suthitha and N. Lokeshwaran

Composite floor is widely used in the building construction. These floors are fabricated by providing steel decks at the bottom portion and reinforced concrete at the top. It provides high strength and resistance to abrasion and fire. Even more time can be saved if the floor slabs are cast on permanent steel formwork that acts first as a working stage and then as bottom reinforcement for the slab. Arriving at an economic and efficient angle of steel sheet is one of the important aspects of the design of skew type steel decking. With increase in load, shear bond slip occurs in the tension side of the slab. In order to restrain these forces an efficient angle of steel decking needs to be evolved. The subject of the ongoing research is to determine the load carrying capacity of composite slab i.e. the concrete slab with profiled steel decking by experimental studies. The embossments are provided in the steel sheet in order to increase the shear bond characteristics between the steel sheet and concrete.
