［提要］ 隨著工程結(jié)構(gòu)逐步向大型化、復(fù)雜化、非規(guī)范化方向發(fā)展，對重大工程在其工作期間的安全性能進行實時監(jiān)測已成為研究的熱點課題之一。以深圳市民中心鋼牛腿結(jié)構(gòu)的健康監(jiān)測為研究背景，提出采用模糊模式識別的方法，并系統(tǒng)論述了該方法在工程中的具體應(yīng)用。研究結(jié)果表明，應(yīng)用模糊模式識別方法可有效地對牛腿結(jié)構(gòu)應(yīng)力場狀態(tài)進行時時的在線監(jiān)測，且該方法識別精度高、速度快。

Abstract:With the constructions becoming larger and more complicated, structural health monitoring for some significant engineering is one of the researchful hotspots. The fuzzy pattern recognition is introduced and some relevant concepts are explained. The application of the method is illustrated.The results from the fuzzy pattern recognition method and numerical method indicate that the principle of fuzzy pattern recognition can satisfy the engineering demand effectively.
