Thanks for answers. One more question, when PNA is located in concrete slab I should use as compresive force C=Fy*As or minimal force of this two: Fy*As and n*Qn? I asume that first one, but I want to be sure.

Now it's look I understand. Could You suggest me, because it is my first composite slab, what percentage of composite is frequently used?

So in this example author assumed that beam will be partially composed, am I right? If I want fully composed then I use minimum of C or T, but then I need provide adequate amount of steel connectors on half of beam to get shear capacity bigger than T or C?

Hi, I'm tring to understand how to locate Plastic Neutral Axis in composite beam by Design Example v14.1 Example I.2. Why in choosing shear transfer C=ΣQn there is assumed 50% of minimal C or T? It can't be take into considiration minimal value of C=0.85*fc*Ac and T=AsFy? Thanks for any reply.

@SAIL3 Do You suggest to reinforce somehow corners of column? About what cleaner options You are talking?

@BadgerPE You welded angles (Am I right?) to beam on workshop and then to column on site or everything on site?

@Zondervan I thought about this what is described in definition of Fnw like sandman21 said. @dik I've checked this plastification and the ratio is something about 40% so you are right it is stiff :) However welds will be the biggest issue. I used to design welds with directional method (von...

Thanks Dik for answer, but unfortunately I can't use W-flange profile here. But I am just interesting You suggest to make this to avoid concentrated force on flange or for other reason? Clear curiosity :)

Hi all, I have question about connection like showed in attachment. I used to work with EC codes so for AISC I need support :) I have two HSS cantilevers attached to HSS 6x6x5/8 column and two HSS beams which are extension for cantilevers to create kind of overhanged beams. On cantilevers there...
