A typical concentrically braced frame featuring X-bracing and subject to a lateral load "P" is illustrated in Figure 1. The compression brace (C) is susceptible to in-plane buckling, although out-of-plane buckling is the more common governing condition. In the following discussion, it is assumed that the diagonal braces are continuous and connected at the intersection point. [...]
