Question

A mild steel section forms a diagonal compression brace in a steel work building structure. The compression brace is restrained by a tubular brace at mid-length. All the connections are pinned, about both axes. The section designation and steel grade of the compression brace is an individual parameter. The geometry, X and H as well as the lateral wind load, W, in Figure 4 are also individual parameters. (b)Sketch the possible deflected shapes of the brace for buckling about each axis.State the effective length factors and calculate the effective lengths. (C)which axis the column is likely to buckle about.Define slenderness ratio and calculate the slenderness ratio about both axes. State (d)Calculate the Euler, Rankine and Perry-Robertson buckling loads. Determine whether the Compression brace is adequate for strength according toEN1993. Please note you will need to check compression capacity of the section for the most critical slenderness value only. You are further required to state the efficiency of the section under the described loading in the value engineering process.
Draw diagrams of the four standard cases of effective length, giving theoretical and design values of effective length factors.
