【摘要】 运用预应力技术,发挥钢管混凝土的受力特点,提出一种新的组合结构——预应力钢管混凝土组合结构。它充分利用钢管混凝土、钢结构的特点和预应力技术,使钢管混凝土材料和钢管结构的应用范围扩大。通过受力机理分析,阐述了受弯结构构件的设计方法和构造措施,给出了工程应用实例。最后对目前正在进行的研究工作及其发展方向作了简单介绍。更多还原

【Abstract】 On the basis of prestressed steel structure and composite structure, a new composite structure was proposed, which combines properties of steel and concrete with prestress technique. It widens the application of steel-tube structure. This new structure is especially suitable for the environment of long-span, heavy load and corrosion. A few such plane structures are designed and will be used in a building. At last, the advance and the current research are introduced.更多还原
