WebDec 18, 2024 · 3. Yes, it is better to design for yield than buckling because Euler buckling is a result of instability as opposed to overloading force. Gamma f is determined from Eurocodes which are from extensive research and materials testing. This means yield is safer than buckling because buckling is not predictable nor easily counteracted in design. WebRegarding the specimens with penetrating defects, their failure modes are similar and displayed in Fig. 5 c). For these specimens, local buckling on the steel tubes was found at the defect edge before the specimens reached the ultimate resistances, and the buckling deformation developed rapidly.
