摘 要: 应用动态松弛法对索膜结构进行初始形态分析和静荷载分析。引入刚度调整系数并提出新的参数取值方法。该刚度调整系数能灵活地保证各种不同刚度结构计算的稳定性。在找形分析中引入测地线单元,加速了找形收敛速度。典型算例说明动态松弛法是索膜结构静力分析的有效方法。 The dynamic relaxation (DR) method is applied to the form-finding and static loading analysis of cable-membrane structures. An adjustable stiffness coefficient is introduced to ensure calculation stability. This stiffness coefficient can be simply determined by several tests. In the analysis of Form-finding, the geodesic string is introduced to accelerate the convergence of DR method. The typical example shows that the DR method is an effective method for form-finding and static analysis of cable-membrane structures.
