【摘要】 对往复荷载作用下的中空夹层钢管混凝土构件进行了试验研究,并做子初步的理论分析,计算得出的荷载-位移滞回曲线与试验曲线结果基本吻合。将试验测得的抗弯刚度与各国规程计算的抗弯刚度进行了对比,供设计时参考。
【Abstract】 Double-skin composite members were tested under cyclic lateral load and preliminary studies were given on the tests. The calculated results of load-deformation curves agreed well with those of tests. The flexural stiffness of double-skin composite members obtained from tests was compared with the calculated results using formulae in different design codes.
【Key words】 concrete-filled steel tubes; double-skin; load-deformation hysteretic curves; flexural stiffness;
