WebConcrete-Filled Double-skinned Steel Tubular columns (CFDST) are proved to possess exceptional structural resistance in case of fire and multi-hazard situations. This superior quality of CFDST makes it preferable in long column applications. However, WebOpen: Ideal Pinned Column Buckling Calculator. Where: E = Modulus of elasticity of the material. I = Minimum moment of inertia. L = Unsupported length of the column (see picture below) Note that regardless of the end condition, the critical load depends not on the material strength, but rather the flexural rigidity, EI.
