| 摘 要： | 本文推导了钢管混凝土单阶、二阶组合柱在风载、不定位水中集中荷载、弯矩作用下以及在这三种荷载共同作用下的上柱影响系数.在比较、分析这些上柱影响系数的基础上给出了上柱柱长与组合柱柱长比及上、下柱刚度比的合理设计范围,并对荷载对组合柱上柱影响系数的影响及上柱影响系数与刚度折减系数的关系进行了分析、讨论.

| Abstract: | The paper deduces the up-column influential factors of concrete filled steel tubu-lar one-step and two-step columns under the work of wind forces,unfixed lateralconcentrated forces and moments,as well as under the combined work of the threeloads.On the basis of comparing and analysing these obtained influential factors,it gives the rational design range of H_1/H,H_2/H,I_3/I_1,I_3/I_2,and studies the influ-ence of load magnitude upon up-column influential factors and the correct relation-ship between stiffness-reduction factor and up-column influential factor. |
