Checks for ultimate strength of frames with partially restrained connections require that the non-linear connection characteristics and the P-~, effects be appropriately modelled. This complexity is unwarranted for preliminary design but few alternatives exist. In this paper an alternate approach, utilizing a second-order plastic analysis method called the mechanism curve (Horne and Morris, 1982), is described. This approach results in a simple and reliable estimation of the collapse capacity of the frame. It was found that this ultimate capacity seldom controls since limitations of drift at service loads results in strong, stiff structures that provide an adequate safety margin against stability failures,

Dear all,

I can't find the article, but the reference to it can be found in the book named Handbook of Structural Engineering, Second Edition posted here:
