I have a one-story structure with stacked X-bracing same as the referenced thread above. I am not understanding how it is not a K-brace. The definition from AISC Seismic Design Manual (5.2) states: where a brace frames to a column at a location where there is no out-of-plane support. Is it a K-brace condition?
I don’t think so. A K-brace is a problem because the horizontal component of the brace goes directly into the column creating a bending moment. In a stacked X-frame the horizontal component goes to the brace below which basically provides the out-of-plane support.
Above is a snippet.
