| 摘 要： | 根据钢管混凝土本身固有的特性，它主要适用于轴心受压和小偏心受压，不适用于受弯；用作轴压长柱时，也不能发挥其特性，因而经济效果也不大．为了有效地扩大钢管混凝上的应用范围，作者提出了预应力钢管混凝土．即在钢管混凝土构件中配以高强度预应力部件，施加预应力，以提高构件的承载力．本文介绍了预应力钢管混凝土拱、预应力轴压构件和受弯构件的基本概念、实验结果和经济效益，供设计部门参考和推广．

| Abstract: | Owing to its properties,CFST suits mainly the axial compressive member and small eccentric compressive member but not the bending member. Therefore, CFST has littleecconomic benifit.In culer to enlarge its application scope, this paper puts forward theprestressed CFST,which is to set high-strength prestressed bar in the CFST member toenhance the loading capacily of a member.The paper also introduces the prestressed CFSTarch. the prestressed axial compression member and bending member,their basic concepts,the results of tests and the economic benefits, all of which can be referencefor design institutes. |
