离心钢管混凝土结构是一种新型的钢 -混凝土复合结构 ,它可充分发挥 2种材料的优点。其特性是 :外钢管可借助混凝土内衬管而增强管壁的局部稳定性 ,应力分布由单向受拉变为双向受拉 ,提高了抗拉强度和防腐能力 ;混凝土管可借助钢管对它的“紧箍作用” ,使原单向压力状态变为三向压力状态 ,提高了混凝土的抗压强度。多年来对该结构进行了大量的各种荷载作用下的试验和研究 ,对它的各种连接方式也进行了探索 ,使它能成功地应用于各类塔架结构
Centrifugal CFST structure is a new type of steel-concrete composite structure, which can give full play to the advantages of two kinds of materials. Its characteristics are: the outer tube can be reinforced by concrete lining pipe wall to enhance the local stability of the stress distribution from one-way tension into two-way tension, improved tensile strength and corrosion resistance; concrete pipe can help it through the steel pipe Of the “tight hoop role” so that the original one-way pressure state into three-way pressure state, improve the compressive strength of concrete. Over the years, the structure has undergone a large number of tests and studies under various loads, and various connection ways have also been explored to enable it to be successfully applied to various types of tower structures
