"WebBuckling behavior can be described as bending of a structure under axial compressive load. As it is well known, columns are the slender structural members that support the axial compressive loads. If the compressive load excessive, a column may fail by structural instability called buckling. Hence, the problem of buckling of steel columns is very " - Buckling of columns คือ
