The deflection and deformation of slender column and eccentrically loaded column of ultro-high strength concrete filled steel tubes under loading were studied.

对钢管超高强混凝土长柱、偏压柱在荷载作用下的挠度及变形特点进行了研究。

Formula to compute nonlinear deflection at the top of the column subjected to both axial and transverse bending is then derived.

然后，推导出承受纵横弯曲塔身顶部的非线性变形计算公式。

The equation used to calculate deflection ductility of columns was obtained, which based on the axial compression ratio and hoop characteristic value of a column.

确认分析效果后，对试件进行了计算机模拟的参数分析，得到基于配箍特征值和轴压比的位移延性计算公式。
