Prediction of Properties of FRP-Confined Concrete Cylinders Based on Artificial Neural Networks
Recently, the use of fiber-reinforced polymers (FRP)-confinement has increased due to its various favorable effects on concrete structures, such as an increase in strength and ductility. Therefore,
Shear strength estimation of reinforced concrete beam–column sub‐assemblages using multiple soft computing techniques
The aim of the present study is to propose innovative predictive models for shear capacity of reinforced concrete (RC) exterior joints in terms of multiple soft computing techniques. Existing models
Modeling of Confined Circular Concrete Columns Wrapped by Fiber Reinforced Polymer Using Artificial Neural Network
It was found that the fundamental behavior of confined concrete columns can logically be captured by the neural network model and provided better results than the analytical and experimental models.
Artificial Neural Networks (ANN) Based Compressive Strength Prediction of AFRP Strengthened Steel Tube
An artificial neural network (ANN) based model is used to estimate the compressive strength, maximum stresses and strains of AFRP strengthened circular hollow section steel tubes under axial compression to reduce computation time and labor.
GFRP wrapped concrete column compressive strength prediction through neural network
