2 Applications Examples Typical application of X-HVB shear connector with steel deck, e.g. new construction. Typical application of X-HVB shear connector with jack arch system (without steel deck), e.g. rehabilitation project.

3 Reduction factors for profile metal decks 1 x 1,5 Ribs transverse to beams Note: k t 1.0 k t = K N r h sc EN designs: K = 0.70 N r = X-HVBs / rib ( in the calculation even if 3 are placed in a rib) AIS, IS, BS 5950, other design codes: K = 0.85 N r = X-HVBs / rib (1, or 3) Ribs parallel to beams for 1.8 k p = 1.0 for < 1.8 k p = 0.6 x h sc Note: k p /

4 Engineering advice onnector placement along the beam The X-HVB is a flexible connector and may be uniformly distributed between critical sections. These critical sections, where large changes in shear flow occur, may be at supporting points, points of application of point loads or areas with extreme bending moments. Partial shear connection Strength: The minimum connection depends on the design code used: a) In EN design, N/N f must be at least 0.4. This increases depending on span length and decking geometry. b) In AIS, N/N f must be at least 0.5. c) In IS, N/N f must be at least Deflection control only: If the shear connection is needed for deflection control only, there is no minimum degree of connection. However, minimum allowable connector spacing applies and the steel beam must have enough strength to carry the self-weight and all imposed loads / 015

5 Application requirements Thickness of base material Thickness of fastened material 8 Minimum thickness of steel base material t II = 8 mm In rehabilitation projects, application to thin beam flanges of minimum 6 mm is possible in order to take the use of small I-sections (e.g. IAO 100 or IPN 80) into account. Please refer to Socotec approval or contact Hilti for detailed information. 1 x 1.5 Maximum thickness of decking t I = 1.5 mm onnector positioning, spacing and edge distances General positioning or or Position the X-HVBs so that the shear force is transferred symmetrically to the beam. X-HVB orientation parallel to the axis of the beam is preferred. Positioning on metal decks - ribs transverse to beam 1) One, two or three X-HVBs per rib Parallel to beam Perpendicular to beam 06 /
