摘　　要：膜结构是近年来兴起的新型大跨度空间结构,本文介绍了动力松弛法的基本理论,推导了采用中心差分数值显式积分法的动力松弛法的基本公式,通过算例表明了该方法在膜结构找形分析应用中的准确性及适用性。Membrane structures, as a type of span structure, have been gradually developed in recent years. In present study, based on theory of dynamic relaxation method, basic form-finding formulae of dynamic relaxation method for form-finding analysis of tension structures are reviewed. some examples are studied, and the results show that the present method is reliable and robust.

关 键 词：动力松弛法 膜结构 运动阻尼 找形
