I thought they were supposed to be different methods as well, but if you place equation 14-5 into 14-4 you get equation 14-6...so they seem to be the same.
However, if they are the same method, I'm not happy with the way it is presented.
Thank you both for the responses.
If these equations are part of the same "method", then this portion of the code makes more sense, but I don't understand why they would show the development of the direct calculation equation. It seems to be redundant.
On top of that, I sent this exact...
Section 14.8.3 of the alternative design of slender walls for ACI 318-02 (as well as '05 and '08) states that the moment at the midheight section of the wall due to factored loads and P-Delta effects (Mu) can be obtained by iteration of deflections using equations 14-4 and 14-5 or by direct...
