Comparative Analysis of Reinforced Concrete Beam Behaviour: Conventional Model vs. Artificial Neural Network Predictions.

Behaviour of First Crack Load Based on a/d The behaviour of the first cracking load with the increasing shear span to an adequate depth (a/d) ratio while keeping the reinforcement ratio constant to 0.349% shows a decreasing trend.

Behaviour of First Crack Load Based on the Reinforcement Ratio The constant value of the shear span to the effective depth ratio (a/d = 1) with an increasing reinforcement ratio (%) (from the graph in Figure 9 ) shows an increasing trend at up to 0.984% reinforcement ratio, which then decreases among the beam samples, while for the same sample value of experimental results, ANN results and theoretical results go on a decreasing trend, respectively.
