There are there types of shear connection between a profiled steel sheet and a concrete slab. At first, reliance was pleed on the natural bond between the two. This is unreliable unless separation at the interface (uplift)is prevented so sheets with re-entrant profiles such as Hologram, were developed , This type of sheer connection is known as frictional interlock. The second type ismechanica in terlock, provided by k,provided by pressing dimples or this (Fig 2.8) into the sheet. The sheet. The effectiveness of these embossments depends entirely on their depth which must be accurately controlled during manufacture. The third type of shear connection is end anchorage. This can be provide where the end of a sheet rests on a steel beam, by means of shot-fired pins, or by welding studs through the sheeting to the steel flange.
