摘要
本文利用有限元法、共轭法对具有侧向水平弹性约束的轴心受压构件临界力的计算方法进行了分析和推导，所建立的理论计算方法概念明确、计算简便．为进行中心配索式预应力钢管混凝土结构的轴压构件临界力计算奠定了理论基础。
Based on the finite element method and the false structure method, this paper analyses and deduces the calculating method for the critical pressure of axil pressure members with lateral elastic supports. The theory calculating method established is clear and definite, which lays a theory foundation for the analysis of axial pressure members of prestressed concrete filled steel tubular structure.
