【摘要】 先介绍了索杆张拉集成体系在实际工程中的应用，然后推导动力松弛法计算不稳定体系的公式，讨论迭代收敛性，给出计算过程。结果表明时间增量，阻尼系数，结点质量及构件刚度对计算的收敛性影响较大。动力松弛法计算过程简单，是计算不稳定体系的一种可选方法。更多还原

【Abstract】 Cable Strut system is a economical structue form.This paper introduces at first its application in engineering.Then some formulas for calculaling the unstable system are derived by using dynamic relaxation.The iterative convergence is discussed and a procedure is given.The results show that the effect of time increment,damping,mass and stifness is larger on calculating.The process of calculation is simple,so dynamic relaxation is a usefull method for analyzing tensegrity system.更多还原
