摘要
滑移索在工程实践中得到了广泛应用,然而在当前的通用有限元程序中却没有相应的计算单元,因此本文提出了一种张力分配与温度补偿的计算方法,该方法可以利用通用有限元中已有的单元类型实现滑移索的准确计算。算例分析验证了这种方法的有效性。
Sliding cables have being used in some special spatial structures. However, there are no exactly corresponding element types in universal program of FEM. Therefore, a method of tension distribution and temperature compensation was proposed in this paper. This method can analyze the sliding cables accurately by using the existed element types in universal program of FEM. The sliding cable segments are assumed to be immobile elements. The method was verified by a numerical example.
