Maximum Slenderness Ratio for a Member Carrying Compressive Loads
Slenderness ratio is the ratio of the effective length of a column to its least radius of gyration. It is an important parameter to determine the stability of a column under compressive loads. The maximum slenderness ratio for a member carrying compressive loads resulting from dead and imposed load should be equal to 180.
Explanation
When a column is subjected to compressive loads, it tends to buckle or bend sideways. This buckling can cause the column to fail even if the compressive stress acting on the column is below its yield strength. The ability of a column to resist buckling depends on its slenderness ratio. The slenderness ratio is calculated as L/r, where L is the effective length of the column and r is the least radius of gyration of the column section.
For a given material and cross-sectional area, the column's maximum slenderness ratio is the ratio at which it will fail by buckling. The maximum slenderness ratio for a member carrying compressive loads resulting from dead and imposed load should be equal to 180. This means that if the slenderness ratio of a column is more than 180, it will fail by buckling even if the compressive stress on it is less than its yield strength.
Conclusion
In conclusion, the maximum slenderness ratio for a member carrying compressive loads resulting from dead and imposed load should be equal to 180. This is an important parameter to determine the stability of a column under compressive loads, and it is essential to ensure that the slenderness ratio of a column is within the allowable limit to prevent buckling and failure.
