Maximum Slenderness Ratio
Maximum Slenderness Ratio
(OP)
Hi,
Does anybody use, as a rule of thumb, a maximum slenderness ratio for concrete columns even though structurally a slender column can work?
Thanks

As a preliminary design, you should use the minimum allowed area of steel to determine the area of column. This way, at the end of the design if you find the column needs more capacity then you can only increase the area of steel to achieve this.

Was that your intention?
Unless you have very tall architectural columns carrying little load, kl/r will almost never approach 100. I had a job recently in which it exceeded 100 and a detailed second order analysis was required, but these were architecural columns that were very small in cross-section due to having very little load (and the look the architect was going for).
If these columns had any significant load on them, the section would have needed to be bigger and the slenderness ratio would have come way down.
