Local buckling can be prevented by(a) limiting width-thickness ratio(b

1.	Local buckling can be prevented by(a) limiting width-thickness ratio(b) increasing width-thickness ratio(c) changing material(d) changing load on memberI got this question in an international level competition.My question is from Beam Types and Sections in portion Design of Beams of Design of Steel Structures
Answer» Correct OPTION is (c) changing material The best explanation: Local BUCKLING of compression members of beam causes loss of INTEGRITY of beam cross SECTION. It is a function of width-thickness RATIO and can be prevented by limiting width-thickness ratio.
