預應力索梁結構形成過程分析

Numerical analysis of the formation process of a prestressed cable-beam structure

  • 摘要: 采用增量形式的平衡方程,建立了有限索單元平衡迭代列式.對一個張拉整體結構中所采用的預應力索梁結構模型進行了全過程數值模擬,并對該結構的受力特點及張拉過程中荷載效應進行了分析.其重點是結構中關鍵結點的初位移的施加方法以及整體性能的控制.結果表明,該結構中梁形成一定程度的反拱對結構的整體穩定性及形成較為均勻的內力分布有一定的積極貢獻.

     

    Abstract: Formulations of the mixed cable-beam finite element method suitable for simulating a prestressed cable-beam structure were presented based on the incremental form of the virtual work principle, The attention is mainly paid to the interaction in constructing the prestressed cable-beam structure and the optimization of structure performance. Key point is to enforce initial displacements by adjusting the position of specified points in the structure. By using the proposed method, the whole process of constructing a prestressed cable-beam structure was simulated. The numerical results demonstrate that the proposed method is feasible.
