1.	The buckling strength of latticed column is ___________ that of solid column having ame area and same slenderness ratio(a) smaller than(b) greater than(c) equal to(d) cannot be comparedThis question was addressed to me in an online quiz.My doubt stems from Elastic Buckling of Slender & Built-up Compression Members in section Design of Compression Members of Design of Steel Structures
Answer» Right choice is (a) smaller than Easy EXPLANATION: The buckling strength of latticed column is smaller than that of solid column having same AREA and same slenderness ratio provided that solid column does not buckle locally because of thinness of material. This is because SHEAR component of axial load produces deformation in lattice which tends to reduce overall stiffness of column and THEREFORE reduce buckling strength of column.
