In addition, the complex localized and global failures characterizing these structural members have led researchers to focus on the development of efficient design guidelines. This paper aims to propose an artificial neural network (ANN) model with optimal architecture to predict the load\u2010carrying capacity of CSB with a scheme of the simple beam bearing load located at the center of the beam. The ANN model is built with 9 input variables, which are essential parameters equivalent to the geometrical properties and mechanical properties of the material, such as the overall depth of the castellated beam, the vertical projection of the inclined side of the opening, the web thickness, the flange width, the flange thickness, the width of web post at middepth, the horizontal projection of inclined side of the opening, the minimum web yield stress, and the minimum flange yield stress. The output variable is the load\u2010carrying capacity of the CSB. With the optimal ANN architecture [9\u20101\u20101] containing one hidden layer, the performance of the ANN model is evaluated based on statistical criteria such as <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>, RMSE, and MAE. The results show that the optimal ANN model is a highly effective predictor of the load\u2010carrying capacity of the CSB with the best value of <jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>\u2009=\u20090.989, RMSE\u2009=\u20093.328, and MAE\u2009=\u20092.620 for the testing part. The ANN model seems to be the best algorithm of machine learning for predicting the CSB load\u2010carrying capacity.<\/jats:p>","DOI":"10.1155\/2021\/6697923","type":"journal-article","created":{"date-parts":[[2021,5,31]],"date-time":"2021-05-31T01:53:07Z","timestamp":1622425987000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Investigation of ANN Architecture for Predicting Load\u2010Carrying Capacity of Castellated Steel Beams"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4266-1707","authenticated-orcid":false,"given":"Thuy-Anh","family":"Nguyen","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8038-2381","authenticated-orcid":false,"given":"Hai-Bang","family":"Ly","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4157-7717","authenticated-orcid":false,"given":"Van Quan","family":"Tran","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,5,30]]},"reference":[{"key":"e_1_2_10_1_2","unstructured":"ZhouX.
