应用Newmark方法编制了空间网架动力弹塑性动力响应分析程序；改进并得出了一种动力缩减方法──考虑静残余的荷载相关Ritz矢量方法，编制了相应的弹塑性动力响应分析程序；为了检验缩减方法（Lcad－dependentRitzVectorsNewmark）的计算精度。用2种方法对同一空间桁架结构进行了计算，结果表明缩减方法具有较好的精度和可靠性。
A dynamic elasto-plastic dynamic response analysis program for a space network was established using the Newmark method. A dynamic reduction method was developed and a load-dependent Ritz vector method considering static residuals was used to formulate a corresponding elasto-plastic dynamic response analysis program. The accuracy of the test reduction method (Lcad-dependentRitzVectorsNewmark) is checked. Two methods are used to calculate the same space truss structure. The results show that the reduction method has better accuracy and reliability.
