円形CFT断面の累加強度と終局強度の比較

抄録

The purposes of this study are to present the formula for calculating the ultimate flexural strength of a circular CFT section, to clarify the relationship between the generalized superposed strength and ultimate flexural strength, in addition, the relationship between the generalized superposed strength and simple superposed strength. Numerical calculation based on the theoretical analysis is performed and moment -axial load interaction relations are shown. Comparing the ultimate strength with superposed strength, the effects of analytical parameters on the strengths are discussed.
