چکیده	The objective of this study is to accurately evaluate pile bearing capacity without the use of sophisticated fnite element software or wave recording by utilizing artifcial neural networks and public pile driving analysis (PDA) test data. The data from 46 concrete piles in Bandar Imam and 65 steel piles in Asaluyeh will be examined using reliable tests. This article used PDA test data and a system made up of two kinds of artifcial neural networks to achieve acceptable results for the pile capacity after introducing previously established relationships. In this system, the pile capacity for a chosen number of piles was fnally determined by successfully combining a number of neural networks. The suggested system extends earlier neural networks for a comparable function and uses a self-organizing neural network for a set of data in training, testing, and valid datasets. Model predictability increased by 80% when parameters like hammer drop height were added. Cross-sectional area and pile length were additional improvements, and a normalized stifness parameter provided marginal gains. However, better results were obtained when length and area were used independently. In the end, predictions were greatly improved by introducing a Bearing Capacity Index (BI) from classical equations. The suggested model is built on this index and PDA data, which provides the best prediction accuracy and efciency for fguring out pile loadbearing capacity.
