This study was carried out from, 1999 through 2001, and discussed a reliability-based design method of structures. The study referred to the design criteria of the United States, Canada, and European countries, because these countries already have introduced the limit state design based on reliability theory. In 1999 and 2000, the reliability-based design criteria of Europe, the United States, and Canada were investigated, and the study discussed an outline of the reliability-based design used for civil and architectural structures in Japan, based on ISO2394. In 2001, we carried out a basic study to realize an easy and effective criterion of the practical reliability-based design.On the other hand, the practical design should not require difficult knowledge and it should be easy for practical design engineers to understand the criterion. Then, the study proposed a new design system, which made use of computational techniques. It is necessary to take good advantages of artificial life technologies (A-Life Technology) of not only the analysis based on the probabilistic theory but also new information processing technology (IT), fuzzy theory, genetic algorithm (GA), neural network technology (NN), cellular automata (CA), and immunity system (IS), etc. in order to improve the structural reliability. This study tried to utilize NN, GA, CA, and IS to treat uncertainty problems that were difficult to solve by using probabilistic theory.

本研究于1999年至2001年期间进行，并探讨以可靠度为基础的结构设计方法。研究参考了美国、加拿大和欧洲国家的设计准则，因为这些国家已经引入了基于可靠度理论的极限状态设计。在1999年和2000年，欧洲，美国和加拿大的可靠性为基础的设计标准进行了调查，该研究讨论了基于ISO2394的可靠性为基础的设计用于土木和建筑结构在日本的大纲。2001年，我们进行了一项基础性研究，以实现实用可靠性设计的一个简单有效的准则，另一方面，实用设计不需要复杂的知识，并且实用设计工程师应该容易理解该准则。然后，本研究提出了一个新的设计系统，它利用了计算技术。为了提高结构的可靠性，不仅要充分利用基于概率论的分析方法，而且要充分利用新的信息处理技术、模糊理论、遗传算法、神经网络技术、元胞自动机、免疫系统等人工生命技术。本研究尝试利用神经网络、遗传算法、元胞自动机及免疫系统来处理一些用机率理论难以解决的不确定性问题。
