Application of artificial neural networks and multiple linear regression on local bond stress equation of UHPC and reinforcing steel bars
Abstract We investigated the use of an Artificial Neural Network (ANN) to predict the Local Bond Stress (LBS) between Ultra-High-Performance Concrete (UHPC) and steel bars, in order to evaluate the accuracy of our LBS equation, proposed by Multiple Linear Regression (MLR). The experimental and numer...
