Part 10: Technical Software Specification for Composite Beams 10 - 10 The profiled steel sheeting, if used, is defined by its section geometry (Figure 2.2): h p is the overall depth of the profiled steel sheeting t p is the sheeting thickness b s is the distance between centres of adjacent ribs b r is the width of rib b b is the width of the bottom of the rib. b s h p b b t p b r Figure 2.2 Cross-section of a profiled steel sheeting One of the following options has to be selected:  Ribs perpendicular to the beam  Ribs parallel to the beam axis. When the profiled steel sheeting is perpendicular to the beam axis, one of the following options has to be selected:  Studs welded through the profiled steel sheeting  Profiled steel sheeting with holes for studs  Profiled steel sheeting interrupted on the beam (free positioning of the studs along the beam axis). 2.4 Shear connection 2.4.1 Description of a stud The connectors are headed studs welded on the upper flange of the steel profile. For a given beam, all the studs are identical. A stud is defined by: h sc is the overall nominal height. d is the shank diameter that can be selected from the following list: – 16 mm – 19 mm – 22 mm f u,sc is the ultimate limit strength of the stud material.
