Is the only way to differentiate between short and long coloums according to ACI is through slendeness ratio? Is there an easier approach?
Hi dear Ali Al-rubiay
The behavior of the slender column and short column is different. Their failure mechanism is not the same either. Look at the picture I attached.
Dear Ali,
Columns can be broadly classified as short and slender columns based on their slenderness ratio. The slenderness ratio of a concrete column is defined as the ratio of its effective length le to its least lateral dimensions. The effective length is the unsupported length multiplied by a factor usually specified in the design codes depending on the end conditions of the column. Each code has its own criteria for classifying columns as either short or slender.
In this regard, I am attaching a thesis, where all the details have been given in more detail. I hope this will help.
Regards,
Pravin
The slenderness ratio has been arrived at by several experimental studies that column will behave as short column or long column on the basis of this. This is globally accepted norm. Similarly when vertical load is dominating then it is sort column and when moment also starts dominating due to deformation of column then this become slender column.
