03.27: Punching shear behaviour of an innovative connection between steel tubular column to flat concrete slab
This paper presents the results of an experimental investigation into the punching shear behaviour and resistance of a simple and effective method of connection between steel tubular column and concrete flat slab using welded shear studs. The shear stud used is the same type as used in conventional steel/concrete composite beams. A major difference between the shear stud behaviour in the proposed system and in composite beam is that in the proposed system, the amount of concrete available to resist punching shear is limited due to small depth of the flat concrete slab. The experimental studies have investigated the effects on punching shear behaviour and resistance of the proposed shear connection system under different design variables including concrete depth above the shear stud, concrete grade, and shear stud dimensions (length and diameter). The results indicate that it is possible to use the proposed simple connection system to provide sufficient punching shear resistance in realistic flat slab construction. Punching shear resistance is dependent on the concrete depth above shear stud. Concrete grade is also important, however, it is the concrete tensile strength that directly determines punching shear resistance. The dimensions of shear stud have relatively minor influences.
