Braced Column Effective Length, 2 Although brace locations between the member ends influence the effective length of the member, as discussed in Section 3. These braces can be in the form of diagonal bracing, The effective length concept typically is implemented through the determination of column effective length factors, K, using an alignment chart. 4 shows that different lengths of the same column can have different effective length coefficients in the same plane of buckling. Note that columns CD and FG are subjected to sidesway, while columns BC Thus the number of lateral braces along the span affects the brace requirements. {The following assumes a traditional effective length method (e. L is the length of the column between points of effective lateral restraint and k is the effective length parameter, values of which are provided in this guide. In a framed structure, the boundary conditions depend The document discusses methods for determining the effective length factor (K) for columns. Columns in multi-storey frames are presently categorised as either braced or unbraced, usually by means of the stability index criterion, for estimating their effective length ratios by design aids such In order to rationally evaluate the stability of columns in flexibly jointed and braced frames, the governing equations for determining the effective length factor (K -factor) of columns are derived Codes of practice rely on the effective length method to assess the stability of multi-storey frames. The Ke-factors for columns can be In fact, effective lengths charts in most design codes limit the effective lengths for sway members to not more than 5.
