【Abstract】 Taking the inherent frequency as the characteristic parameters of input, the depth and position of crack fault in simply supported steel beam was diagnosed and forecasted, applying artificial neural network(ANN). It showed that it is feasible to synthetically diagnose and forecast the crack fault in structure using artificial neural network.更多还原
