The Load and Crack Width Model for Partially Prestressed Concrete Beams Based on Neural Network

The initiation and propagation of cracks in concrete structure are very complex and to some extent, and it is difficult to model it in a regularway. Amodel based on neural network, which is good at association and generalization, is proposed to study the relationship between the crackwidth and the applied load in partially prestressed concrete beams. The model is verified by some test results with satisfaction.
