预应力钢管混凝土柱受力行为的分析研究

The Study of Prestressed CFST Column

本文针对钢管混凝土偏心受压柱的特点,提出了施加预应力将其转化为准轴压柱的设计概念,基于连续介质力学,分析了预应力钢管混凝土柱的受力全过程及承载能力,提出了设计准则和设计方法.

<ABSTRACT> According to the peculiarity of CFST column, the conception of utilization prestress bar to improvement its behaviors is proposed,based on continuous medium mechanics, the theory of ultimate strength is conducted, moreover, the design criterion and method is given,which lay a theory foundation for prestressed CFST column.
