WebIn structural engineering, buckling is the sudden change in shape (deformation) of a structural component under load, such as the bowing of a column under compression or the wrinkling of a plate under shear.If a structure is subjected to a gradually increasing load, when the load reaches a critical level, a member may suddenly change shape and the … Webpost for each column. It is important to stop the loading of the column as soon as the critical load has been reached to avoid permanent damage to the column. For each …
