The inconsistent excitation can be decomposed into a series of irregular incident waves in terms of the spectral decomposition scheme of the hermitian matrix , with which the coherency function of the ground motions under the inconsistent excitation can be obtained numerical results are given to show its stability and rationality 该方法将随机输入下的波动分析问题转换为多个虚拟激励下的确定性波动分析组合问题，从而可以方便地获得场地波动观测量之间的谱密度矩阵，进而计算给出工程场地的地震动相干函数本文还用数值模拟的办法对所提出方法的合理性和稳定性进行了探讨。
The stable distributions of shenzhen stock sub - index ( szsi ) and shanghai stock composite index ( shci ) are discussed , and the portfolio problems of probability criterion and chance - constrained programming are also analyzed . the main contents and results are as follows : 1 . the basic theories of univariate stable distribution and multivariate stable distributions and stable stochastic processes are introduced 本文对深圳成分指数（ szsi ）以及上海综合指数（ shci ）的稳定分布、概率准则投资组合问题以及机会约束投资组合问题进行了研究，主要内容及研究结果如下： 1 .介绍了一元稳定分布以及多元稳定分布与稳定随机过程的基本理论。
3 . discuss the combination from member damage to structure damage and difference of global damage index for weigh coefficient ; 4 . two times poa - based global damage model that includes synthetically stiffness , intensity and ductibility degrading by equivalent stiffness decay before and after damaged is presented and is compared with weigh method 3 ）分析由构件损伤指数到结构整体损伤指数的组合问题，及其由不同的加权系数选择造成结构整体损伤指数的差异； 4 ）通过基于两次推倒分析的结构整体刚度退化损伤模型，选取结构的等效刚度退化来定义结构的整体损伤模型，并同加权法进行比较； 5 ）通过按照规范设计的框架结构，按照基于损伤性能的设计理论进行抗震损伤设计校核。
