What is the Equivalent Column Concept?

It is accepted that the deflected axis of any column may be represented by a portion of the column deflected shape of axially loaded pin-ended column. Therefore, for a given column subjected to end moments, an equivalent column exists and the column deflected shape of the equivalent pin-ended column can be represented by sinusoidal curve.

What are the Different Modes of Failure of RC Columns?

There are three modes of failure of concrete columns (compression members) i.e., failure due to pure compression, combined compression and elastic instability. This concept is adopted in order to reduce uni-axially loaded columns to an axially loaded equivalent pin-ended column with greater length.
