简介：混合模拟是为评估结构的系统的地震性能的一个强大的测试方法。这个方法使，结构的仅仅批评的部件试验性地被测试，可行。这份报纸为被瞄准扩大它的能力到存在方法遇到一些限制的大量系统的地震混合模拟论述一个最新建议的集成算法。在建议方法，它被称为可变时间步(vt)集成方法，一个含蓄的计划被在试验性的元素上消除反复的阶段为混合模拟采用，在常规含蓄的应用必要的阶段。以便学习VTS方法的有效性，一系列数字调查被进行它在获得精确、稳定、收敛的回答显示出VTS方法的成功。在一条比较途径，然后，在通常使用的集成方法上的VTS方法的改进精确性被表明。VTS方法的稳定性也被学习，结果证明它提供有条件的稳定性；然而，它的稳定性限制在精确性限制以外好。VTS方法结果上的时间延期的效果也被调查，VTS方法在处理这个试验性的错误是相当成功的，这被显示出。
