Temporary fixing of metal decking

BCSA agreed a programme of work with the Building Research Establishment (BRE) in 2019 to carry out a series of dynamic wind tests on steel decking sheets, followed by a series of wind tunnel tests for both high-rise and portal frame type structures. The aim of this project was (i) to determine the possible loads taken by the individual fixings connecting the decking to the steelwork during the temporary fixed construction stage, and (ii) to propose a simplified methodology based on BS EN 1991-1-4 for the design of such fixings. Recommendations are given at the end of this document for practical construction in the UK.
