摘 要: 应用动态松弛法 ,计算索网结构的位移和拉力。根据理论分析 ,给出时间增量和阻尼系数的一个取值公式 ,从而解决了以往凭经验选取这两个重要参数的困难。 The dynamic relaxation method is applied to the static analysis of cable nets. According to the theoretical analysis, two important formulas are presented to determine the time incrementΔt and damping coefficient Ci. So that the difficulty of selecting these two important parameters can be overcome. Typical examples and the experimental results are presented to show the efficiency and the accuracy of the method.
