摘要
通过总结国内外对于预应力结构、钢结构以及钢管混凝土组合结构的研究和应用成果,在简要论述基础上,提出一种新的组合结构型式———预应力钢管混凝土组合结构。本文针对预应力钢管混凝土桁架,通过其受力机理分析,阐述了其设计方法和构造措施,给出了工程应用实例。并对目前正在进行的研究工作及发展方向作了简单探讨。
On the basis of prestressed steel structures, concrete filled steel tubular/rectangular (CFST/CFSR) structures and composite structures, a new kind of composite structure named prestressed CFST/CFSR structure (PCFST/PCFSR) has been proposed, which combines the properties of steel and concrete with prestressing technique. It widens the application of steel structure and CFST(CFSR) structure. This paper simply elucidates the design procedure and the construction measures of PCFST spatial truss by analysis of its mechanical properties and mechanism. An application example is given. Finally, the development and the current research have been introduced.
