    Hello, Saadat! If you have Ned / Npl,Rd >= 1,0 then your member is failing in compression, thus, there is no need to check interaction as cross-sections resistance is already insufficient for axial load alone. Have a great day, Reinis

    The particular one you posted is just a commentary and does not contain a pdf file or similar. There are some AD's that are written in this way and are posted only as written info, others are pdf. All AD's are quite short, 1 to possibly 3 pages. Cheers

    You can try this one: https://www.amazon.de/Typisierte-Anschlüsse-Stahlhochbau-nach-1993-1-8/dp/3941687123/ref=sr_1_4?s=books&ie=UTF8&qid=1474352477&sr=1-4&keywords=Typisierte+Anschlüsse+im+Stahlhochbau it is great and covers a lot of steel connections, but it is in German.

    The problem in some aspect is the same as for monolith reinforce concrete ribbed slabs (T beams with effective flange width). The moments you get in your steel beam from FEA are smaller than the ones you need to design your T beam for. In simple terms you need to design your composite T beam for a moment that is equal to the moment in the beam (from FEA) + the integrated moment in the slab within the effective flange width at the particular sections. For example if you have a beam moment of 100kNm and the effective flange width is 1,2m, with an average moment of 10kNm/m in that effective width your design moment is 100kNm + 1,2m*10kNm/m = 112kNm. In general effective flange width are large and thus the effect of slab moment increases the design moment compared to the steel beam moment quite significantly. For some more definitive guidance particular to reinforced concrete you should read in the "Finite-Element Design of Concrete Structures - 2nd Edition" by G.A. Rombach - really good book! Cheers

    Deflections will be proportional to actions and if I remember correctly (you'll need to check code for specifics) the classification will take account of this relative stiffness, not the actual amount of deflection for some particular load case. In any case you'll check the buckling for highest horizontal forces and smallest vertical forces.
