本研究的目的是阐明方形 CFT 梁柱在恒定轴向载荷下承受恒定循环位移的横向载荷的循环行为。测试参数为有效长断面深度比、轴压比和转角幅值。显示了横向载荷和旋转角度的关系、轴向应变行为和载荷恶化行为。讨论了轴向应变行为和载荷恶化行为之间的关系。此外，将实验荷载与CFT建议中所示的截面强度、极限强度和许用强度进行了比较，并讨论了实验荷载与荷载劣化行为之间的关系。
The objective of this study is to clarify the cyclic behavior of square CFT beam-columns subjected to lateral load with constant cyclic displacement under constant axial load. Test parameters are the effective length-section depth ratio, axial compression ratio and rotation angle amplitude. The lateral load and rotation angle relationships, axial strain behaviors and load deterioration behaviors are shown. The relationship between the axial strain behaviors and load deterioration behaviors are discussed. Moreover, the experimental load is compared with the section strength, ultimate strength and the allowable strength shown in the CFT Recommendations and the relationship between the experimental load and load deterioration behaviors are discussed.
