摘要
本文采用模糊似然推理原理,对引起模糊性的因素进行定量化分析,客观地评价了结构的安全性。基于这种评价的结构优化设计,不但经济,而且安全可靠,其结果更符合实际情况。以拱坝优化设计为例,取得了较为满意的结果。
The factors which cause fuzziness are analysed quantitatively and the Safety of Structure is assessed objectively by means of the principle of fuzzy reasoning. The structure optimization design based on this assessment is not only economical but also safe and liable. Take the example of optimization design of arch dam, the results are satisfying.
