I have a frame where the method of lateral force resistance consists of (entirely) moment connections. Rather than go through and figure all the K-values for the members, I thought that I might just set all the K-values equal to 1 and do a analysis & design considering the p-delta affects. Do you consider this feasible? After all, isn’t that what the K-values attempt to compensate for (i.e. increased moments from p-delta)?

(As you’ve probably already guessed: the program I am using for analysis can do a p-delta analysis very easily, but the k-values have to be figured manually.)


 
In my previous post, for some reason question marks appear wherever I posted P-? for local member deformation effects of P-delta..
