Webb22 mars 2024 · The effective length of a column, , is the length between points of inflection on the deflected curve/shape (even if the shape must be extended until a point of inflection is reached – discussed below). For a column pinned at both ends, the effective length is simply the full length of the column between pin restraints: WebbThe effective length of the column depends on its support reaction or end restrained. 1. If the end of the column is effectively held in a position restrained against rotation at both ends = 0.5 L. 2. If the end of the column is effectively held in position at both ends and restrained against rotation at one end =0.7 L. 3.
