| 摘 要： | 钢管混凝土受弯构件的滞回曲线和不发生局部失稳的钢构件相同，具有良好的抗震性能。Ｐ－滞回曲线和骨架曲线分为无下降段和有下降段两种情况。建议限制构件的长细比可以不控制构件的轴压比。因而钢管混凝土用作高层建筑的框架柱具有突出的优点。

| Abstract: | It is verified that the M- hysteresis loops of CFST bending members are similarly with that for steel members without local buckling. It has good aseismic behaviors. From the M- relationships, the P- hysteresis loops and skeleton curves can be derived, there are two kinds of P- skeleton curves, no- descending and with descending stages. Author has suggested to limit the slenderness ratio of member instead of limiting the axial compressive ratio. Hence, CFST has prominent advantages if it is adopted as the columns in tall buildings. |
