6.2 - Design rules for minimum degree of connection

Back to main Contents page

Composite beams with metal decking should be designed in accordance with BS EN 1994-1-1 or BS5950-3 Section 3.1:1990 +A1 2010. However, recent industry research undertaken by SCI and BCSA has resulted in non-contradictory complementary information that provides the designer with advanced rules for design of composite beams removing the conservatism that exists with the current ‘catch all’ rules contained in both BS EN 1994-1-1 and BS5950-3 Section 3.1:1990 +A1 2010.

The SCI/BCSA research provides the designer with advanced rules that cover wider design criteria than that currently available in the relevant design standards, including:

• Unpropped construction

• Partially utilised beams

• Beams with large web openings

Refer to SCI Publication P405: Minimum degree of shear connection rules for UK construction to Eurocode 4
