The studies of the safety of structures must incorporate concepts covering three subareas. A perfect part, where St. Venant's principle is invalid; and errors in design and construction, which occur in both parts. This project is concerned with the identification of such errors in the field and their inclusion, in a blind fashion, into laboratory tests of imperfect parts. A group of experts are used to offer opinions concerning the capacity of the parts after simulated seismic loading, which has not been extended to destruction. The experts are asked to suggest remedial measures as well as verbal opinions of the structural competence. Continuing loading to failure will provide a measure of success of such opinions. Where possible Bayesian statistics will be used, but where the axioms of probability theory are not satisfied, reliance is made on fuzzy set theory.

结构安全性研究必须结合概念 涵盖三个子领域。 一个完美的部分，圣维南的原则 是无效的;和错误的设计和建设，这发生在两个 零件. 该项目涉及识别此类 错误的领域和他们的列入，在盲目的方式， 不完美部件的实验室测试。 一组专家习惯于 对模拟后的部件能力提出意见 地震荷载，这还没有扩展到破坏。 的 专家们被要求提出补救措施，以及口头 结构能力的观点。 继续加载至失效 将提供一个衡量这种意见是否成功的标准。 在可能的情况下 贝叶斯统计将被使用，但在概率公理 理论的不足，依赖模糊集理论。
