Abstract : on the basis of reliability theory , cutting - of f - tail distributio n has been applied into limit state method in this paper 文摘:根据可靠性理论，这里将截尾分布应用于极限状态法中。
Secondly , the failure mode of bottom plates for finite element calculation is put forward based on the definition of ultimate states 其次，依据极限状态的定义，给出了适用于有限元计算的底板失效模式。
In recent years , it is terrible increasingly of the stabilization of power system as that power system runs more closely to terminal state 近年来，随着电力系统运行更加接近极限状态，电力系统的稳定问题日趋严重。
In the modern ship construction design research realm , people pay more and more attention to the ultimate strength of ship hull girders 在现代船体结构设计的研究领域中，船体梁的极限状态分析已愈来愈受到人们的重视。
The paper deduced the deformation and flexural bearing capacity formula by the theory of elasticity - plasticity , ultimate - state method 本文分析研究中用弹性理论、弹塑性理论、极限状态方法推导组合板受弯承载力和变形计算公式。
The failure mode and the design reference period of the steel rail are discussed , and the steel rail ' s performance function at limit state is established too 讨论了钢轨的失效模式和设计基准期，建立了钢轨极限状态方程的功能函数。
Test result suggests , in the serviceability limit states , displacement is littleer , the plane stiffness infinite assumption may be established 实验结果表明，在正常使用极限状态时，位移较小，同一楼层平面内刚度无限大的假定可以成立。
So each pile does n ' t enter the limit state simultaneously and therefore it is necessary to study the reliability of the group piles 事实上，桩基础中各桩的桩顶反力并不相同，因而各桩并非同时进入极限状态。因此有必要对群桩的可靠性进行研究。
Equation of limit stat e method and method of calculating reliability has been established , along with combination of distribution variables commonly used 建立了截尾分布的极限状态方程和计算可靠度的算法，给出了常用截尾分布随机变量组合的公式。
Secondly , the fuzzy limited state equations of the bolts and flange rings are determined according to a limited load method and their fuzzy reliabilities are calculated 然后，按照极限载荷法确定螺栓与法兰环的模糊极限状态方程，并计算其模糊可靠度。
