张拉索膜结构找力分析的复位平衡法

Using Reposition Balance Method to Find Tensility Structures' Prestress

根据自然界中的相似原理提出了复位平衡法的思想,结合非线性有限元的变形分析实现了对张拉索膜结构的找力分析。和解析解比较的结果显示这种找力分析的方法有很高的计算精度。从而给形面构造和实际结构的预应力诊探提供了新的探索方向和研究方法。

Based on the similarity principle in nature, the idea of reposition balance method is put forward. This method, which is combined with deforming analysis used nonlinear finite element method, is used to compute the balance prestress of tensility structures. Compare the results with the analytic solution, it showed that this method had very high precision. This method indicates a new way for form-constructing and the prestress-diagnosing on the made membrane structures.
