简介：这研究由于地震刺激在结构的倒塌的上下文为大、复杂的结构的系统的混合模拟检验集成方法的表演。目标申请未必为即时测试，但是相当为包含大规模物理基础的模型和高度非线性的数字模型。四案例研究被介绍并且讨论。在第一案例研究，也就是，包括二个广泛地使用的方法的集成计划的精确性与重复的改正数字修改了含蓄的Newmark的版本(反复)并且切开操作员(非反复)通过纯数字模拟被检验。第二案例研究介绍模拟为反复的集成方法就各种各样的时间步和重复的改正数字而言与二个上述的集成方法重复了的10混血儿的结果。在这些测试的物理基础由single-degree-of-freedom(SDOF)组成有提供可重复的highlynonlinear行为包括的可替代的钢赠券的伸臂列破裂类型力量和僵硬降级。以防学习三，有重复的改正数字的含蓄的Newmark被申请1:2的混合模拟放大包括一个相对复杂的非线性的数字基础的钢时刻框架。最后，一个更复杂的数字基础被构造联合到一个1:2规模钢严肃框架的一个混合模型的一个片刻框架的一个非线性的计算模型考虑。最后二案例研究在一样的porotype结构和步和重复的固定数字仔细在预告测验模拟被检验的时间的选择上被进行。产生失衡力量被用作一个索引追踪平衡错误并且预言模拟的精确性和稳定性。

简介：这个地点和结构的参数无常的动态效果的考虑被标准在大多数国家为核电厂(NPP)要求。抗地震的标准提供二个基本方法分析参数无常。手工地直接处理计算地板反应系列(皇家学会会员)确定的途径珍视是第一个方法。第二个方法是执行概率统计的FRS的分析根据蒙特卡罗方法结果。二个方法能仅仅反映不明确的参数的全面效果，并且结果不能为某个参数影响和贡献被屏蔽。在这研究，基于NPP的地板反应系列的动态分析，为各种各样的不明确的参数的估计的影响的一个全面索引被介绍并且推荐，包括关联系数，回归斜坡系数和旋风秋千。在NPP地震标准补偿指导的缺乏，建议方法能有效地被用来从敏感，尖酸和统计秋千的方面评估各种各样的参数的贡献关联。最后，例子被提供从系统、直觉的观点验证指示物的集合，例如NPP的皇家学会会员的结构参数和贡献的影响的无常。这个索引对参数的不同类型敏感，它为评估为NPP要求的抗地震的参数提供一种新技术。
