How to calculate the allowable slenderness ratio of steel structures under compression?
The slenderness ratio is in the majority of cases for the component, and the formula coffee has given. As for the concept, it is easy to see from the formula that the slenderness ratio is the ratio of the length of the member to its corresponding radius of gyration.
The slenderness ratio of the structure is I = l/i, and the radius is gyration radius.The buckling stress in the axial compression members of steel structures is only related to slenderness ratio.
It can be seen from the formula that the concept of slenderness ratio takes into account the end constraint of the component, the length of the component itself and the section characteristics of the component.The effect of slenderness ratio on the stability calculation of compressive members is obvious, because the larger the slenderness ratio is, the more easily it is unstable. Here are some formulas for calculating axial and flexural members. There are parameters related to slenderness ratio.
