A steel section is to be used as a column, it is to have a slenderness ratio of 88 and it has an overall length of 6m. Calculate the radius of gyration and hence select from the table of standard steel sections, a suitable universal column 'I' section. Using this specification of the column determine the compressive stress induced for an axial load of 200kN

Do you know what the slenderness ratio is?
Engineer: StructuralEng, Bachelor's Degree replied 1 year ago
It is kL/r. Assume k=1.0. L=6m (change this to mm or cm, depending what units your r is in). Set that equal to 88 and solve for r. This is the required radius of gyration to reach a slenderness ratio of 88.
Engineer: StructuralEng, Bachelor's Degree replied 1 year ago
Then, based on the slenderness ratio, determine the allowable compressive stress on the column. From this, determine how much area you need and select a column that meets the r value and A value.

Hi
Thank you for your help so far, i dont understand what you mean by set that equal to 88

The goal of this site is not to give engineering lessons. I can help you with very specific questions, but it&#39;s not practical to give an engineering lesson. I suggest you talk to your professor.
