6.5 - BS5950-3 Section 3.1 Reduction factors for SMD Products

These figures are calculated in accordance with the latest revision of BS5950-3 Section 3.1:1990 +A1 2010. The factors in this table should be applied to the minimum resistance for a stud in a solid slab (Qk) from Table 5 of BS5950-3 Section 3.1:1990 +A1 2010.

: 1 = Figures are based on 95mm LAW shear studs except TR80+ which is based on 120mm LAW.

: 2 = All factors are based on ‘mesh at nominal top cover’, except Parallel which is based on ‘below head of stud’

Refer to SCI Publication PN001a-GB NCCI: Resistance of headed stud shear connectors in transverse sheeting

Refer to SCI Publication PN002a-GB NCCI: Modified limitation on partial shear connection in beams for buildings

Refer to SCI AD380: What Height of Shear Stud Should be used in Eurocode 4

Refer to SCI AD174: Shear connection along composite edge beams
