Joist notching into Steal Column

[Glanmor]

Hi all,
quick roofing/decking question...
6m flat roof devided in the middle by UC Steel colum, 3m josts either side. 6m wide.
UC is 152x152x30 and joists are 47x150mm approx.
After joists notched in to steel beam there is few mm gap at the top edge of each joist and steel. Is there an official way to remedy that gap or is it just force some timber in there. Was worried that left alone would allow wind uplift to lift the roof by that small gap distance.
Thanks.

A smaller gap than that between each joist then!

The bigger concern is the potential cold bridge, so remember the insulation.

Presumably this is a warm roof, otherwise how is it vented?
