AD 512: Eurocode requirements for wind bracing connections

AD 509 reminded designers that according to BS 5950, preloaded assemblies are not required when reversal is solely due to wind loading. The AD recommended that this guidance is equally appropriate for design to the Eurocode.

In fact, BS EN 1993-1-8 provides the same advice in clause 2.6(3). The Eurocode notes that for wind and/or stability bracings, bolts in Category A connections may be used. Category A connections are “bearing type”, more commonly known as ordinary bolts in clearance holes. No preloading is required for Category A connections
