| 摘 要： | 本文以多层厂房稳态响应符合正态分布的各态历经过程为理论基础,探讨了通过数值积分求稳态响应样本函数及响应方差的可行性,编制两个程序,对三个实际厂房计算分析。解决了多层厂房整体竖向振动非数定分析中的若干问题,使该方法可以用于解决工程实际问题。计算分析表明,非数定分析方法不但在理论上正确、可行、而且在计算精度和计算时同上明显优于传皖的振型迭加法。

| Abstract: | This paper discusses the feasibility to obtain response sample functions and response variances by using the step by step integration procedure, based on the theory that the steady-state response of plant buildings corresponds to the ergodic process of the normal distribution, Some problems are solved, which are encountered in nondeterministic analysis of the overall vibrations of the multistoriod plant buildings. Computations,analysis and comparisons show that the nondeterministic analysis method is practical and effective. It has some advantages over the traditional mode-super-position method. |
