even though it's in dutch, should be useful.
This shows where the .92 ; .96; ... comes from.
Before one applies these formules, make sure you thoroughly understand the preconditions and limitations that comes with each situation.

Hello, I have one doubt.....
Lets say I want to make T joint both side fillet welded from 8 and 16 mm thick plates ;
now I can make 2 arrangement:
1) 16 mm plate horizontal and 8 mm plate vertical (both side weld to 8 mm plate)
2) 8 mm plate horizontal and 16 mm plate vertical (both side weld to 16 mm plate)
so for both cases (both side) fillet leg size will be 6 mm (0.5*8/0.7)
or it will be 6 mm(0.5*8/0.7) for case 1 and 8 mm (0.5*16/0.7=11.43 mm but smaller plate being 8 mm thick) for case 2 ???
I am a bit confused?
I also read section 11 not long ago. As I know LW is often used in bridges and hi-rise buildings. Advantage of weight reduced by high price and little smaller strength.
About your question... I think the answer is increase of LW strength class or increase of diameter and number of shear stirrups. As I know, there is no other options for standard RC design (non-pretensioned) in EN2.
Wait for your lecturer answer
