Without damaging the structure, it can effectively evaluate the uniformity and relative quality of concrete structures. Ultrasonic Pulse Velocity has some advantages such as the low cost, easier to operate and convenient to carry. But, using UPV test to estimate concrete compressive strength have an average of over 20% mean absolute percentage error (MAPE) when comparing to the actual compressive strength obtained by destructive the tests. As a result, this research collected a total of 312 sample data from a material testing laboratory in Chia-Yi. The collected data are used to train and validate the concrete strength prediction model developed by this research. Firstly, linear and nonlinear regression prediction models are developed and then three artificial intelligence techniques, artificial neural network (ANN), support vector machine (SVM) and adaptive neural fuzzy inference system (ANFIS), are adopted to develop the AI prediction models. The objective is to establish a best prediction model for the UPV test. The results show that both of the MAPEs for the linear and nonlinear regression models are 11.17% and 17.66% respectively. The MAPEs for ANFIS, ANN and SVM models are 9.86%, 10.94% and 10.495% respectively. The research results can provide valuable information when UPV tests are used to estimate concrete compressive strength. WANG,YU-REN 王裕仁 2016 學位論文 ; thesis 105 zh-TW
