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.
