Are uncertain and should be regarded as random variables, therefore the reinforced concrete frame is stochastic structure inherently, and then its motive equations converted to combined random differential equations for the uncertain parameters and external random excitation. these equations were solved by order - orthogonal expansion method with pseudo - excitation method, and then the statistic stochastic responses of random structure were obtained. at last, based on the stochastic cumulative damage model with double parameters developed by park, formulas were formulated for calculating structural earthquake damage probability using the structural reliability theory ( mainly jc algorithm ) in extensive random space
首先對受地震激勵的剪切型鋼筋混凝土結構進行建模，用隨機等效線性化方法將二階非線性微分方程組化成一階線性微分方程組（或稱之為狀態方程） ；再考慮材料等參數的隨機性，則狀態方程成為復合隨機微分方程組，將擴階系統方法和虛擬激勵方法推廣並應用於這個復合隨機微分方程組，求出結構的隨機響應量的統計參數；最後採用隨機累積損傷破壞準則，在廣義隨機空間內，用jc演算法求解失效概率，進而求出結構的抗震可靠度。 -
When the performance degradation is caused by the discrete cumulative damages, the degradation failure model based on renewal process is proposed and used to analyze the reliability of metallized film pulse capacitors in the laser device. when the degradation process is continuous, two models based on wiener - einstein and gamma processes are presented respectively. because it is difficult to obtain an analytical expression of the failure model using the latter method, we present a failure model based on monte - carlo simulation
根據該模型的特點，給出了基於參數回歸分析的統計推斷方法，分別提出基於比例危險模型的競爭失效分析方法和基於位置-尺度模型的競爭失效分析方法; （ 4 ）對于隨機失效閾值問題，研究並給出了相對失效標準下的退化失效模型和分析方法;對強度退化的動態應力-強度干涉失效進行分析，提出了周期性應力作用下的動態應力-強度干涉失效可靠性模型和復合應力作用下動態應力-強度干涉失效可靠性模型。 -
The concepts of degradation failure and the framework of reliability analysis from degradation measurements have been discussed. the inference methods for the repeated - measures degradation data are proposed. the performance degradation is caused by interior damage cumulative processes of products that may be discrete or continuous
（ 3 ）對于突發失效與退化失效的競爭失效問題，在考慮突發失效與產品性能退化過程相關時，提出了一個競爭失效的模型，該模型包括了突發失效與退化失效無關時的情況。
